Explanation:
Statement 1: Igneous rocks are parent rocks and also known as primary rocks.
This statement is correct. Igneous rocks are formed from the solidification of molten material, either magma or lava. They are considered parent rocks because they can give rise to other types of rocks through the process of weathering, erosion, and sedimentation.
Statement 2: Acidic igneous rocks have lower quantity of silica content whereas Basic igneous rocks have more silica content.
This statement is incorrect. The silica content in igneous rocks determines whether they are classified as acidic or basic. Acidic igneous rocks, also known as felsic rocks, have a higher silica content, while basic igneous rocks, also known as mafic rocks, have a lower silica content. Therefore, the statement should be reversed.
Statement 3: Sedimentary rocks contain layers or strata, therefore often known as stratified rocks.
This statement is correct. Sedimentary rocks are formed through the accumulation and lithification of sediments, which are often deposited in layers or strata. These layers can provide valuable information about the geological history of an area.
Statement 4: Shale, Marble, Quartzite are some common metamorphic rock types.
This statement is incorrect. Shale is a common sedimentary rock, not a metamorphic rock. Marble is a metamorphic rock formed from the metamorphism of limestone, while quartzite is a metamorphic rock formed from the metamorphism of sandstone. Therefore, the statement is partially correct as it includes two metamorphic rock types (marble and quartzite) but also includes a sedimentary rock (shale).
Conclusion:
From the given statements, only statement 1 and statement 3 are correct. Therefore, the correct answer is option 'C' - 1 and 3 only.

Igneous rocks are parent rocks and also known as primary rocks.
Acidic igneous have more silica e.g Granite, whereas Basic igneous rocks have lower quantity of silica , e.g. Gabbro.
Sedimentary rocks contain layers or strata, therefore often known as stratified rocks.
Shale is not a metamorphic rock, its mechanically formed sedimentary rock. Marble, Quartzite, Slate, Schist, Gneiss are some common metamorphic rock types.
Hence, both statements 1 and 3 are correct.
