Assertion: Placenta in addition to connection with mother and foetus is ductless gland.
Reason: It releases human gonadotrophins.

Options

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

Answer

### Step-by-Step Solution:

1. **Understanding the Assertion**: The assertion states that the placenta is a ductless gland in addition to its role in connecting the mother and fetus.
- **Explanation**: The placenta serves as a vital organ during pregnancy, facilitating the exchange of nutrients and waste between the mother and fetus. It also functions as an endocrine organ, meaning it releases hormones directly into the bloodstream without using ducts.

2. **Understanding the Reason**: The reason given is that the placenta releases human gonadotropins.
- **Explanation**: Human gonadotropins, such as human chorionic gonadotropin (hCG), are hormones produced by the placenta. These hormones play crucial roles in maintaining pregnancy and supporting fetal development.

3. **Evaluating the Assertion and Reason**: Both the assertion and the reason are correct statements.
- **Assertion Validity**: The placenta does act as a ductless gland (endocrine gland) because it secretes hormones.
- **Reason Validity**: The placenta does release human gonadotropins, which are essential for pregnancy.

4. **Determining the Relationship**: While both statements are true, the reason does not directly explain why the assertion is true.
- **Explanation**: The assertion is about the placenta being a ductless gland due to its endocrine functions, while the reason specifically mentions human gonadotropins, which is just one of the many hormones produced by the placenta.

5. **Conclusion**: Since both the assertion and reason are true, but the reason does not correctly explain the assertion, the correct answer is that both the assertion and reason are true, but the reason is not the correct explanation of the assertion.

### Final Answer:
Both assertion and reason are true, but the reason is not the correct explanation of the assertion.
