Question

Assertion (A): The mammary glands secrete milk for the nourishment of the young ones.

Reason (R): These are modified sweat glands.

Options

• Both (A) and (R) are true and (R) is the correct explanation of (A).

• Both (A) and (R) are true, but (R) is not the correct explanation of (A).

• (A) is true, but (R) is false.

• (A) is false, but (R) is true.

Answer 1

Both (A) and (R) are true and (R) is the correct explanation of (A).

Explanation:

Since milk is secreted by the mammary glands to feed the young, assertion (A) is accurate. Since mammary glands are modified sweat glands that developed from sweat glands to make milk, reason (R) is equally accurate. The claim and the justification are connected as the mammary glands have evolved to secrete milk rather than perspiration despite having a similar ancestor to sweat glands.
