Assertion : Cockroach has two pairs of legs and three pairs of wings.
Reason: Legs are used to jump while wings are used to fly.

Options

A. If both Assertion and Reason are true but Reason is not a correct explanation of Assertion
B. If both Assertion and Reason are true but Reason is not a correct explanation of Assertion.
C. If Assertion is true but Reason is False
D. If both Assertion and Reason are false

Answer

### Step-by-Step Solution:

1. **Understanding the Assertion**: The assertion states that "Cockroach has two pairs of legs and three pairs of wings."
- **Evaluation**: This statement is incorrect. A cockroach actually has three pairs of legs (totaling six legs) and two pairs of wings.

2. **Understanding the Reason**: The reason states that "Legs are used to jump while wings are used to fly."
- **Evaluation**: This statement is also incorrect. Cockroaches do not primarily use their legs to jump; they use them for walking and climbing. Additionally, while cockroaches can glide using their wings, they are not strong fliers.

3. **Conclusion on Assertion and Reason**: Since both the assertion and the reason are false, we need to determine the correct answer option based on this evaluation.

4. **Analyzing the Options**:
- Option 1: Both assertion and reason are true and reason is the correct explanation of assertion. (Incorrect)
- Option 2: Both assertion and reason are true. (Incorrect)
- Option 3: Assertion statement is false. (Partially correct, but does not address the reason)
- Option 4: Both assertion and reason are false. (Correct)

5. **Final Answer**: The correct answer is Option 4: Both assertion and reason are false.
