Answer 1

(2)

Explanation:

Cretinism affects children, not adults. It results from severe deficiency of thyroid hormones during early development and may cause stunted physical growth and intellectual disability. Therefore, the Assertion (A) is false.

Cretinism is a form of hypothyroidism caused by defective development or early degeneration of the thyroid gland. Therefore, the Reason (R) is true.

Hence, A is false and R is true.
