• C. A is true and R is false.
• D. A is wrong and R is true.

Hint:

Differentiate between reflexive initiation and voluntary action in the digestive system's final steps.

The Correct Option is A

Egestion is a voluntary process as it is under conscious control. The urge to defecate arises due to reflex initiated by the presence of waste in the rectum, which makes the Reason a correct explanation of the Assertion.
