Question

Arrange the following stages of oogenesis in order of their occurrence:
(A) Ovum
(B) Oogonia
(C) Primary oocyte
(D) Secondary oocyte
Choose the correct answer from the options given below:

• A. (C), (B), (D), (A)
• B. (B), (C), (D), (A)
• C. (D), (C), (A), (B)

Answer 1

The Correct Option is B

(A) Ovum

The ovum is the final product of oogenesis. It is a mature egg cell that is ready for fertilization.

(B) Oogonia

Oogonia are the initial cells that give rise to the oocytes. They are the starting point of oogenesis.

(C) Primary oocyte

The primary oocyte is formed from the oogonia. It undergoes meiosis I to form the secondary oocyte.

(D) Secondary oocyte

The secondary oocyte is formed from the primary oocyte after meiosis I. It undergoes meiosis II to form the ovum.

Conclusion

The correct order of the stages of oogenesis is (B) Oogonia, (C) Primary oocyte, (D) Secondary oocyte, (A) Ovum. Therefore, the correct answer is (2) (B), (C), (D), (A).
