Question

Assertion (A): There are three major types of rocks.

Reason (R): The rocks have been classified in three categories on the basis of their characteristics.

Options

• Both A and R are true and R is the correct reason for A.

• Both A and R are true but R is not the correct reason for A.

• A is true and R is false.

• A is false and R is true.

Answer 1

Both A and R are true and R is the correct reason for A.

Explanation:

Rocks are broadly classified into three major types, igneous, sedimentary, and metamorphic, based on their formation process and characteristics. Hence, the classification is indeed based on their characteristics, making both the assertion and the reason true, with the reason correctly explaining the assertion.
