Answer

To solve the question regarding the assertion and reason about the relationship between fig trees and wasps, we can break it down into the following steps:

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "Fig and wasp cannot complete their life cycle without each other." This suggests a dependency between the two species.

**Hint**: Consider how both organisms might rely on each other for survival and reproduction.

2. **Understanding the Reason**:
- The reason provided is that "It is a mutualistic relationship." A mutualistic relationship is one where both species benefit from the interaction.

**Hint**: Think about what benefits each organism gains from their relationship.

3. **Analyzing the Relationship**:
- In the case of fig trees and wasps, the fig tree requires the wasp for pollination. The wasp, in turn, lays its eggs inside the fig fruit, which serves as a food source for the developing larvae.

**Hint**: Identify the specific roles of each organism in this relationship.

4. **Conclusion**:
- Since the fig tree cannot reproduce without the wasp's pollination and the wasp relies on the fig for reproduction and nourishment, it confirms that they cannot complete their life cycles without each other. Therefore, both the assertion and the reason are correct.

**Hint**: Reflect on how the mutual benefits reinforce the assertion.

5. **Final Answer**:
- Based on the analysis, the correct answer is that both the assertion and the reason are correct, and the reason is a correct explanation for the assertion.

### Final Answer:
Option A: Both assertion and reason are correct, and the reason is the correct explanation for the assertion.
