A: Phenol and formaldehyde are momers of Bakelite.
R: Bakelite is used for making combs.

Options

A. If both Assertion & Reason are true and the reason is the correct explanation of the assertion, then mark 1.
B. If both Assertion & Reason are true but the reason is not the correct explanation of the assertion, then mark 2.
C. If Assertion is true statement but Reason is false, then mark 3.
D. If both Assertion and Reason are false statements the mark 4.

Answer

To solve the question, we need to analyze the assertion and the reason provided, and determine their validity and relationship.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "Phenol and formaldehyde are monomers of Bakelite."
- This statement is true because Bakelite is indeed synthesized through the polymerization of phenol and formaldehyde. The process involves the condensation reaction where water is released, leading to the formation of a polymer.

2. **Understanding the Reason**:
- The reason states that "Bakelite is used for making combs."
- This statement is also true. Bakelite is a thermosetting plastic that is widely used in various applications, including the manufacture of combs, due to its durability and heat resistance.

3. **Analyzing the Relationship**:
- While both the assertion and the reason are true, we need to determine if the reason provides a correct explanation for the assertion.
- The assertion explains what Bakelite is made of, while the reason explains one of its uses. The reason does not explain why phenol and formaldehyde are the monomers of Bakelite; it simply states a fact about its application.

4. **Conclusion**:
- Since both the assertion and the reason are true, but the reason does not serve as a correct explanation for the assertion, we conclude that the correct answer is that both statements are true, but the reason is not the correct explanation for the assertion.

### Final Answer:
The correct answer is: **Both assertion and reason are true, but the reason is not the correct explanation for the assertion.**
