The minerals include the native metals copper and gold, and many sulfides, oxides, and hydroxides. Minerals in these groups are generally good ore minerals because they contain relatively large amounts of the desired elements.

Explanation:
The incorrect option is option C: The mineral content of the ore must be in sufficient concentration to make its extraction commercially viable.

Reasoning:
- Minerals are usually formed in "ores": Ores are naturally occurring rocks or minerals that contain a valuable substance that can be extracted for profit. Minerals are often found in ores and are extracted through mining and processing.
- The term 'ore' is used to describe an accumulation of any mineral mixed with other elements: Ores can contain a mixture of minerals and other elements. For example, iron ore contains iron mixed with other elements such as oxygen and sulfur.
- The type of formation or structure in which they are found determines the relative ease with which mineral ores may be mined: The geological formation or structure where mineral ores are found can affect the ease of mining. For example, ores found in shallow deposits near the surface may be easier to mine than those found deep underground.

Incorrect Option:
- The mineral content of the ore must be in sufficient concentration to make its extraction commercially viable: This statement is incorrect because the mineral content of an ore does not necessarily have to be in sufficient concentration to make its extraction commercially viable. Some ores may have low mineral concentrations but still be economically viable to mine and extract due to factors such as the demand for the mineral, the cost of extraction, and the availability of technology.

Example:
- Bauxite is an ore that contains aluminum mixed with other elements. The mineral content of bauxite is relatively low, but it is still commercially viable to extract aluminum from bauxite due to the high demand for aluminum and the availability of efficient extraction methods.

Conclusion:
The incorrect option is option C because the mineral content of an ore does not have to be in sufficient concentration to make its extraction commercially viable. Other factors such as demand, cost, and technology can also determine the commercial viability of extracting minerals from ores.

Read the extract and answer the questions that follows:Minerals are usually found in “ores”. The term ore is used to describe an accumulation of any mineral mixed with other elements. The mineral content of the ore must be in sufficient concentration to make its extraction commercially viable. The type of formation or structure in which they are found determines the relative ease with which mineral ores may be mined. This also determines the cost of extraction. It is, therefore, important for us to understand the main types of formations in which minerals occur.Minerals generally occur in these forms:(i) In igneous and metamorphic rocks minerals may occur in the cracks, crevices, faults or joints. The smaller occurrences are called veins and the larger are called lodes. In most cases, they are formed when minerals in liquid/molten and gaseous forms are forced upward through cavities towards the earth’s surface. They cool and solidify as they rise. Major metallic minerals like tin, copper, zinc and lead etc. are obtained from veins and lodes.(ii) In sedimentary rocks a number of minerals occur in beds or layers. They have been formed as a result of deposition, accumulation and concentration in horizontal strata. Coal and some forms of iron ore have been concentrated as a result of long periods under great heat and pressure. Another group of sedimentary minerals include gypsum, potash salt and sodium salt. These are formed as a result of evaporation especially in arid regions.(iii) Another mode of formation involves the decomposition of surface rocks and the removal of soluble constituents, leaving a residual mass of weathered material containing ores. Bauxite is formed this way.(iv) Certain minerals may occur as alluvial deposits in sands of valley floors and the base of hills. These deposits are called ‘placer deposits’ and generally contain minerals, which are not corroded by water. Gold, silver, tin and platinum are most important among such minerals.(v) The ocean waters contain vast quantities of minerals, but most of these are too widely diffused to be of economic significance. However, common salt, magnesium and bromine are largely derived from ocean waters. The ocean beds, too, are rich in manganese nodules.Answer the following MCQs by choosing the most appropriate option.Q. The ocean beds, too, are rich in ______________ nodules.
