Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): During ovulation, the Graafian follicle ruptures to release a secondary oocyte rather than a fully mature ovum. Reason (R): The secondary oocyte completes its second meiotic division within the ovary just prior to ovulation. In the light of the above statements, choose the most appropriate answer f

Options

  1. ABoth Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A)
  2. BBoth Assertion (A) and Reason (R) are true but Reason (R) is not the correct explanation of Assertion (A)
  3. CAssertion (A) is true but Reason (R) is false
  4. DAssertion (A) is false but Reason (R) is true

Correct answer

Assertion (A) is true because during ovulation, the Graafian follicle ruptures to release a secondary oocyte, which is arrested in metaphase II of meiosis, rather than a fully mature ovum. Reason (R) is false because the second meiotic division of the secondary oocyte does not occur in the ovary.
