• B. Both A and R are true and R is the correct explanation of A.
• C. A is true but R is false.
• D. A is false but R is true.

Answer 1

The correct option is D A is false but R is true.

$\bullet$ Excretion is the process of removing unnecessary and waste materials out of the body. As it is excreting materials out of the body, it is a passive process.
$\bullet$ Secretion, on the other hand, is an active process by which molecules are transported from one place to other.
