AI Generated Solution

The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Assertion**: The assertion states that macromolecules are able to move through pores. This is true because macromolecules, such as RNA and proteins, need to pass through nuclear pores to enter or exit the nucleus. 2. **Understanding the Reason**: The reason provided states that at certain places, both membranes of the nucleus get fused to form pores. This is also true. The nucleus has an outer membrane and an inner membrane, and they fuse at specific points to create nuclear pores. 3. **Connecting Assertion and Reason**: The assertion and reason are related. The presence of nuclear pores (formed by the fusion of the inner and outer membranes) allows for the movement of macromolecules. Thus, the reason supports the assertion. 4. **Conclusion**: Both the assertion and the reason are true, and the reason correctly explains the assertion. Therefore, the correct answer to the question is that both statements are true and the reason is the correct explanation for the assertion. **Final Answer**: Both the assertion and reason are true, and the reason is the correct explanation for the assertion. ---
