Assertion : We can never have an isolated north pole or south pole.
Reason : Unlike poles attract and like poles repel each other.

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion.
B. If both assertion and reason are true but reason is not the correct explanation of assertion.
C. If assertion is true but reason is false.
D. If assertion is false but reason is true.

Explanation

To solve the question regarding the assertion and reason provided, we will analyze both statements step-by-step.

### Step 1: Understanding the Assertion
The assertion states that "We can never have an isolated north pole or south pole." This means that in nature, we cannot find a magnet that has only one pole (either just a North Pole or just a South Pole).

**Hint:** Think about how magnets are structured and what happens when you cut a magnet in half.

### Step 2: Understanding the Reason
The reason given is "Unlike poles attract and like poles repel each other." This describes the fundamental behavior of magnets. When you bring two magnets close to each other:
- The North Pole of one magnet will attract the South Pole of another magnet (unlike poles).
- The North Pole of one magnet will repel the North Pole of another magnet (like poles), and the same applies to South Poles.

**Hint:** Recall the basic principles of magnetism and how different poles interact with each other.

### Step 3: Analyzing the Relationship
Now, we need to analyze the relationship between the assertion and the reason. The assertion is about the existence of isolated poles, while the reason explains how poles interact.

- The assertion is true because every magnet has both a North and a South Pole, and if you try to isolate one, you will always end up with both poles.
- The reason is also true as it accurately describes the behavior of magnetic poles.

**Hint:** Consider whether the reason explains why the assertion is true.

### Step 4: Conclusion
While both the assertion and the reason are true, the reason does not provide a correct explanation for the assertion. The assertion is about the impossibility of having an isolated pole, while the reason explains the interaction between poles.

**Final Answer:** Both the assertion and reason are true, but the reason is not the correct explanation for the assertion.

### Summary of Options
Based on the analysis:
- Option 1: Both assertion and reason are true, and the reason is the correct explanation for the assertion (Incorrect).
- Option 2: Both assertion and reason are true, but the reason is not the correct explanation for the assertion (Correct).

**Final Answer:** Option 2 is correct.
