Given below are two statements: One is labelled as Assertion A\mathbf{A} and the other is labelled as Reason R\mathbf{R}. Assertion A: During menstrual cycle, the ovulation takes place approximately on 14th 14^{\text{th }} 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.

Options

  1. AA\mathbf{A} is correct but R\mathbf{R} is not correct.
  2. BA\mathbf{A} is not correct but R\mathbf{R} is correct.
  3. CBoth A\mathbf{A} and R\mathbf{R} are correct and R\mathbf{R} is the correct explanation of A\mathbf{A}.
  4. DBoth A\mathbf{A} and R\mathbf{R} are correct but R\mathbf{R} is NOT the correct explanation of A\mathbf{A}.

Correct answer

C. Both A\mathbf{A} and R\mathbf{R} are correct and R\mathbf{R} is the correct explanation of A\mathbf{A}.

Step-by-step solution

The correct answer is option (3), because in a 28 days menstrual cycle of a human female, rapid secretion of LH leading to its maximum level during the mid-cycle ( 14th 14^{\text{th }} day) called LH surge induces the rupture of Graafian follicle and thereby the release of ovum (ovulation). Hence, both (A) and (R) are correct and (R) is the correct explanation of (A).
