Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R. In the light of the above statements, choose the most appropriate answer from the options given below.
Assertion (A):Intelligence is, to some extent, an inherited characteristic.
Reason (R):Environment also has a significant influence on intelligence.
ABoth A and R are correct and R is the correct explanation of A
BBoth A and R are correct but R is not the correct explanation of A ✓ Correct
CA is correct but R is not correct
DA is not correct but R is correct
Correct answer: (B) Both A and R are correct but R is not the correct explanation of A
Explanation
Intelligence is to some extent an inherited characteristic, since genetic factors contribute to it, so the Assertion is correct.
The environment also has a significant influence on intelligence, so the Reason is correct in itself.
The Assertion states the hereditary contribution, while the Reason states the environmental contribution.
Because the two speak of different sources, the Reason does not explain the hereditary claim of the Assertion.
Intelligence is best understood as the joint product of heredity and environment.
Twin and adoption studies are the classic method used to estimate the heritability of intelligence.
