This question was addressed to me in class test.

This intriguing question comes from Human Reproduction in chapter Human Reproduction of Biology – Class 12

Answer 1

Correct answer is (a) Secondary oocyte and first polar body

For explanation: The primary oocyte is arrested at Prophase I of meiosis, and the division is completed only in the tertiary follicle. This division is asymmetric and produces a large haploid secondary oocyte and a small first polar body.
