Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): During the luteal phase of the menstrual cycle, the endometrium is maintained and prepared for potential implantation. Reason (R): The ruptured Graafian follicle transforms into the corpus luteum, which secretes large amounts of progesterone. In the light of the above statements, choose the most ap
Options
- ABoth (A) and (R) are true and (R) is the correct explanation of (A)
- BBoth (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
Correct answer
A. Both (A) and (R) are true and (R) is the correct explanation of (A)
Step-by-step solution
Assertion (A) is true because the endometrium must be maintained during the luteal phase to allow for the implantation of a fertilised ovum. Reason (R) is true because after ovulation, the remaining parts of the Graafian follicle transform into the corpus luteum. The corpus luteum secretes large amounts of progesterone. Progesterone is the specific hormone essential for the maintenance of the endometrium. Therefore, Reason (R) correctly explains why the endometrium is maintained during the luteal phase as stated in
