B. B,A,C,D,E
C. B,A,D,C,E
D. C,D,E,A,B

Answer

To arrange the steps involved in spermatogenesis in the correct order, we can follow the process step by step:

1. **Step B: Spermatogonia multiply by mitotic division.**
- The process of spermatogenesis begins with spermatogonia, which are the immature male germ cells located in the seminiferous tubules of the testes. These cells undergo mitotic division to produce more spermatogonia.

2. **Step A: Primary spermatocytes undergo the first meiotic division.**
- After the spermatogonia have multiplied, some of them will grow and differentiate into primary spermatocytes. These primary spermatocytes then undergo the first meiotic division, resulting in two secondary spermatocytes.

3. **Step D: Secondary spermatocytes undergo the second meiotic division.**
- The secondary spermatocytes produced from the first meiotic division will then undergo the second meiotic division, resulting in four spermatids.

4. **Step C: Transformation of spermatids into sperms.**
- The spermatids are then transformed into mature spermatozoa (sperms) through a process called spermiogenesis.

5. **Step E: Release of sperms from the seminiferous tubules.**
- Finally, the mature spermatozoa are released from the seminiferous tubules into the lumen of the testes, where they can be transported out of the body.

Putting these steps in order, we have:
- B → A → D → C → E

### Final Sequence:
1. B: Spermatogonia multiply by mitotic division.
2. A: Primary spermatocytes undergo the first meiotic division.
3. D: Secondary spermatocytes undergo the second meiotic division.
4. C: Transformation of spermatids into sperms.
5. E: Release of sperms from the seminiferous tubules.
