Assertion : Electromagnetic waves do not require medium for their propagation.
Reason : They can't travel in a medium.

Options

A. If both Assertion and Reason are true and the Reason is correct expanation of the Assertion.
B. If both Assertion and Reason are true but the Reason is not correct expanation of the Assertion.
C. If Assertion is true, but the Reason is false.
D. If Assertion is false but the Reason is true.

Explanation

To analyze the given assertion and reason, let's break down the statements step by step:

### Step 1: Understand the Assertion
- **Assertion**: "Electromagnetic waves do not require medium for their propagation."
- This statement is **true**. Electromagnetic waves, such as light, radio waves, and X-rays, can propagate through a vacuum without the need for a medium. This is a fundamental property of electromagnetic waves.

### Step 2: Understand the Reason
- **Reason**: "They can't travel in a medium."
- This statement is **false**. Electromagnetic waves can indeed travel through various media, such as air, water, and glass. While their speed may change depending on the medium, they are not restricted from traveling in one.

### Step 3: Conclusion
- Since the assertion is true and the reason is false, we conclude that the assertion stands correct while the reason does not support it.

### Final Answer
- The assertion is correct, and the reason is false.
