A: Nylon -6 is obtained by heating caprolactum with water.
R: It is used for making bristles for brushes.

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 given question, we will analyze both the assertion and the reason provided, and then determine their validity.

### Step-by-Step Solution:

**Step 1: Analyze the Assertion**
- The assertion states: "Nylon-6 is obtained by heating caprolactam with water."
- Caprolactam is a cyclic amide (lactam) that, when heated in the presence of water, undergoes ring-opening polymerization to form Nylon-6.
- This process involves breaking the lactam ring and linking the monomer units together to form the polymer.
- Therefore, the assertion is **true**.

**Step 2: Analyze the Reason**
- The reason states: "It is used for making bristles for brushes."
- Nylon-6 is indeed used in various applications, including textiles and some plastic products, but it is not typically used for making bristles for brushes. Other types of nylon, such as Nylon-66, are more commonly used for this purpose.
- Therefore, the reason is **false**.

**Step 3: Conclusion**
- Since the assertion is true and the reason is false, we conclude that the correct answer to the question is that the assertion is correct, but the reason is incorrect.

### Final Answer:
- The correct answer is option **3**: Assertion is true, Reason is false.
