Question

Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A): Prolactin secretion from adenohypophysis is essential during lactation.
Reason (R): It helps in the ejection of milk from mammary glands.
In light of the above statements, choose the correct answer from the options given below.

• A. Both (A) and (R) are true and (R) is the correct explanation of (A).
• B. Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
• C. (A) is true but (R) is false.
• D. (A) is false but (R) is true.

Hint:

Milk ejection is due to oxytocin, not prolactin.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept
Prolactin from the anterior pituitary builds mammary glands and milk, while oxytocin ejects milk.

Step 2: Check the Assertion
Prolactin is essential for lactation, so (A) is true.

Step 3: Check the Reason
Ejection of milk is by oxytocin from the posterior pituitary, so (R) is false.

Final Answer:
(A) is true but (R) is false. \[ \boxed{\text{(C) }\text{(A) is true but (R) is false.}} \]
