This section contains Assertion (A) and Reason (R) type questions. Each question has choices (1), (2), (3) and (4), out of which only one is correct.
Assertion (A) Spermiation is the transformation of spermatid into sperm.
Reason (R) During spermiation, sperms get nutrition from Sertoli cell

Options

A. Both Assertion and reason are correct, and Reason is the correct explanation of Assertion.
B. Both Assertion and Reason are correct, but Reason is not the correct explanation of Assertion.
C. Assertion is correct, but Reason is incorrect
D. Assertion is incorrect, but Reason is correct

Answer

To solve the assertion and reason question, we will analyze both the assertion (A) and the reason (R) provided.

### Step-by-Step Solution:

1. **Understanding the Assertion (A)**:
- The assertion states: "Spermiation is the transformation of spermatid into sperm."
- **Explanation**: Spermiation is indeed the final stage of spermatogenesis where spermatids, which are immature sperm cells, undergo transformation into mature spermatozoa (sperm). This process involves the shedding of excess cytoplasm and the formation of a tail, allowing the sperm to become motile.

2. **Understanding the Reason (R)**:
- The reason states: "During spermiation, sperms get nutrition from Sertoli cells."
- **Explanation**: Sertoli cells are supportive cells found in the seminiferous tubules of the testes. They provide essential nutrients and support to developing sperm cells throughout the process of spermatogenesis, including during spermiation. This is crucial for the maturation and functionality of the sperm.

3. **Evaluating the Relationship between A and R**:
- Both the assertion and the reason are correct statements.
- The reason (R) provides a valid explanation for the assertion (A) because the nourishment from Sertoli cells is essential for the transformation of spermatids into sperm during spermiation.

4. **Choosing the Correct Option**:
- Based on the analysis, the correct option is:
- (1) Both A and R are correct, and R is the correct explanation of A.

### Final Answer:
The correct choice is (1) Both A and R are correct, and R is the correct explanation of A.
