Given below are two statements: One is labelled as Assertion A and the other is labelled as Reason R.
Assertion A: During menstrual cycle, the ovulation takes place approximately on 14th day.
Reason R: Rapid secretion of LH in the middle of menstrual cycle induces rupture of Graafian follicle and thereby the release of ovum.
In the light of the above statements, choose the most appropriate answer from the options given below.
A is correct but R is not correct.
A is not correct but R is correct.
Both A and R are correct and R is the correct explanation of A.
Both A and R are correct but R is NOT the correct explanation of A.
Both A and R are correct and R is the correct explanation of A.
Solution
Both Assertion A and Reason R are correct, and R provides a valid explanation for A. The LH surge in the middle of the menstrual cycle triggers ovulation.
