Assertion :- Nucleus is the organised structure remains surrounded by continuous membrane.
Reason:- Nuclear membrane is permeable so no need of discontinuities.

Options

A. If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion.
B. If both Assertion & Reason are True but Reason is not a correct explanation of the Assertion.
C. If Assertion is True but the Reason is False
D. If both Assertion & Reason are false.

Answer

To solve the question, we need to analyze both the assertion and the reason provided.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "Nucleus is the organized structure remains surrounded by continuous membrane."
- This statement is partially correct. The nucleus is indeed an organized structure, but it is surrounded by a double membrane known as the nuclear envelope, which consists of an inner and an outer membrane.

2. **Understanding the Reason**:
- The reason states that "Nuclear membrane is permeable so no need of discontinuities."
- This statement is incorrect. The nuclear membrane is not fully permeable; it is selectively permeable. It contains nuclear pores that allow the passage of certain molecules (like RNA and proteins) but does not mean that it lacks discontinuities.

3. **Evaluating the Truth of Each Statement**:
- The assertion is true in that the nucleus is an organized structure, but it is misleading because it suggests a single continuous membrane when in fact there are two membranes.
- The reason is false because it incorrectly describes the nature of the nuclear membrane as fully permeable and disregards the presence of nuclear pores.

4. **Conclusion**:
- Since the assertion is true but the reason is false, the correct option is that the assertion is true and the reason is false.

### Final Answer:
The correct answer is: **Assertion is true and Reason is false.**
