Assertion:Mammalian teeth are heterodont.
Reason: Mammalian teeth are embedded in a socket of jaw.

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion.
B. If both assertion and reason are true but reason is not the correct explanation of assertion.
C. If assertion is true but reason is false.
D. If both assertion and reason are false.

Explanation

To solve the question, we need to analyze both the assertion and the reason provided.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "Mammalian teeth are heterodont."
- Heterodont dentition means that mammals have different types of teeth, such as incisors, canines, premolars, and molars. This is true for mammals, as they possess various types of teeth adapted for different functions (e.g., cutting, tearing, grinding).

2. **Understanding the Reason**:
- The reason states that "Mammalian teeth are embedded in a socket of jaw."
- This refers to thecodont dentition, which is a characteristic of mammals where the teeth are set in sockets in the jawbone. This is also a true statement.

3. **Evaluating the Relationship**:
- Both the assertion and the reason are true statements about mammalian dentition.
- However, the reason provided does not explain why mammalian teeth are heterodont. The presence of different types of teeth (heterodont) is not directly explained by the fact that they are embedded in sockets (thecodont).

4. **Conclusion**:
- Since both statements are correct but the reason does not explain the assertion, the correct answer is that both the assertion and reason are correct, but the reason is not the correct explanation of the assertion.

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