Options

A. Spermatozoa
B. Diploid spermatids.
C. Primary spermatocytes `rarr` Secondary spermatocytes `rarr` spermatids `rarr` Spermatogonia `rarr` Sperms
D. Spermatogonia

Answer

To answer the question about what secondary spermatocytes produce during the second meiotic division in spermatogenesis, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Spermatogenesis**: Spermatogenesis is the process of sperm cell development that occurs in the seminiferous tubules of the testes. It involves several stages: spermatogonia, primary spermatocytes, secondary spermatocytes, and finally, spermatozoa.

2. **Identify the Role of Spermatogonia**: Spermatogonia are the initial germ cells that undergo mitotic division to increase their numbers. They are diploid, meaning they contain two sets of chromosomes (46 chromosomes in humans).

3. **Formation of Primary Spermatocytes**: Some of the spermatogonia differentiate into primary spermatocytes, which are also diploid. These cells undergo the first meiotic division.

4. **Meiosis I - Formation of Secondary Spermatocytes**: During the first meiotic division, each primary spermatocyte divides to form two secondary spermatocytes. At this stage, the secondary spermatocytes are haploid, containing only one set of chromosomes (23 chromosomes).

5. **Meiosis II - Formation of Spermatoids**: The secondary spermatocytes then undergo the second meiotic division (Meiosis II). This division results in the formation of spermatids, which are also haploid.

6. **Final Differentiation**: The spermatids then undergo a process of maturation and differentiation to become spermatozoa (mature sperm cells).

### Conclusion:
The secondary spermatocytes undergo the second meiotic division during spermatogenesis to produce **haploid spermatoids**.

### Answer:
The correct answer is **haploid spermatoids**.
