B. Statement-1 is True, Statement-2 is True, Statement-2 is NOT a correct explanation for Statement-1
C. Statement-1 is True, Statement-2 is False
D. Statement-1 is False, Statement-2 is True

Answer

To solve the question regarding the statements about Nylon-6, we will analyze each statement step by step.

### Step 1: Understand Statement 1
**Statement 1:** Nylon-6 is a step-growth polymer.

- **Explanation:** Step-growth polymerization, also known as condensation polymerization, involves the reaction between functional groups of monomers, leading to the formation of polymers. In this process, small molecules (like water) are eliminated as by-products. Nylon-6 is formed through such a reaction, where the polymerization occurs between monomers containing amine and carboxylic acid functional groups.

### Step 2: Verify Statement 1
- **Conclusion:** Statement 1 is **true** because Nylon-6 is indeed formed through step-growth polymerization.

### Step 3: Understand Statement 2
**Statement 2:** Nylon-6 is obtained from caprolactam.

- **Explanation:** Caprolactam is a cyclic amide (lactam) with six carbon atoms. When caprolactam is heated in the presence of an inert atmosphere (like nitrogen), it undergoes ring-opening polymerization to form Nylon-6. The reaction involves the breaking of the ring structure and the formation of long polymer chains.

### Step 4: Verify Statement 2
- **Conclusion:** Statement 2 is **true** because Nylon-6 is synthesized from caprolactam through the heating process.

### Step 5: Analyze the Relationship Between the Statements
- **Relationship:** While both statements are true, Statement 2 does not provide a correct explanation for Statement 1. Statement 1 describes the type of polymerization, while Statement 2 describes the source of the monomer.

### Final Conclusion
- **Correct Answer:** Statement 1 is true, Statement 2 is true, but Statement 2 is not the correct explanation of Statement 1.

### Summary of the Solution
- Statement 1 is true: Nylon-6 is a step-growth polymer.
- Statement 2 is true: Nylon-6 is obtained from caprolactam.
- Statement 2 does not explain Statement 1.
