Given below are two statements. One is labelled Assertion (A) and the other is labelled Reason (R).

Assertion (A) : Meiosis I of oogenesis results in the formation of a large secondary oocyte and a tiny first polar body.

Reason  (R) : Meiosis I of oogenesis is a reductional division.

In light of the above statements, choose the correct answer from the options given below.

Both (A) and (R) are true but (R) is not the correct explanation of (A).

Meiosis I of oogenesis results in the formation of a large secondary oocyte and a tiny first polar body. This unequal division ensures that the oocyte retains a greater amount of cytoplasm, which plays a crucial role in nourishing the developing zygote.

Meiosis I of oogenesis is a reductional division. This is true but does not explain (A).
