A: During formation of condensation polymers, elimination of small molecules takes place.
R: Nylon -6,6 is a condensation polymer.

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 both the assertion and the reason provided, and determine their correctness and relationship.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "during the formation of condensation polymers, elimination of small molecules takes place."
- This is true because condensation polymers are formed by the joining of monomer units with the elimination of small molecules, typically water or alcohol.

2. **Understanding the Reason**:
- The reason states that "Nylon-6,6 is a condensation polymer."
- This is also true. Nylon-6,6 is indeed a condensation polymer formed from hexamethylenediamine and adipic acid.

3. **Analyzing the Relationship**:
- The assertion explains a general principle about condensation polymers, while the reason provides a specific example of a condensation polymer (Nylon-6,6).
- However, the reason does not directly explain why the assertion is true. The assertion stands independently as a general statement about condensation polymers.

4. **Conclusion**:
- Both the assertion and the reason are correct statements.
- However, the reason does not serve as an explanation for the assertion.
- Therefore, the correct answer is that the assertion is correct, the reason is correct, but the reason is not the correct explanation for the assertion.

### Final Answer:
The correct option is: Assertion is correct, Reason is correct, but Reason is not the correct explanation for Assertion.
