Non-renewable natural resources:
Non-renewable natural resources are those that cannot be replenished or replaced within a short period of time. They are formed over millions of years and their availability is limited. Once these resources are depleted, they cannot be easily replenished. Examples of non-renewable resources include fossil fuels like coal, oil, and natural gas, as well as minerals like iron, copper, and aluminum.

Explanation:
The correct answer is option 'B' - non-renewable. This means that most of the natural resources we consume at our homes or in our cars are non-renewable. Here's an explanation of why this is the case:

1. Fossil fuels:
Fossil fuels, such as coal, oil, and natural gas, are widely used for heating, electricity generation, and transportation. These resources were formed from the remains of plants and animals that lived millions of years ago. Fossil fuels are finite resources that are being consumed at a faster rate than they are being formed. Once these resources are depleted, they cannot be easily replaced.

2. Minerals:
Many minerals are also non-renewable resources. These include metals like iron, copper, and aluminum, which are used in the construction of buildings, vehicles, and appliances. These minerals are extracted from the earth's crust through mining processes. However, mining can be destructive to the environment and the extraction of minerals is not sustainable in the long run.

3. Renewable resources:
While there are some renewable resources, such as solar and wind energy, that can be used to power our homes or cars, they are not as widely used as non-renewable resources. Renewable resources can be replenished naturally over a relatively short period of time, making them more sustainable. However, their availability and efficiency still have limitations, which is why they are not the primary sources of energy for most households and vehicles.

In conclusion, the majority of the natural resources we consume at our homes or in our cars are non-renewable. These resources are limited in supply and their extraction and consumption have negative impacts on the environment. It is important to conserve these resources and explore alternative, sustainable options for energy and materials.
