Assertion : Microwaves are better carrier of signals than optical waves
Reason : Microwaves move faster than optical waves.

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 both assertion and reason are false

Explanation

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

**Step 1: Analyze the Assertion**
- The assertion states that "Microwaves are better carriers of signals than optical waves."
- In reality, optical waves, particularly those transmitted through optical fibers, are known to carry signals with higher bandwidth and lower loss compared to microwaves. Therefore, the assertion is **false**.

**Step 2: Analyze the Reason**
- The reason states that "Microwaves move faster than optical waves."
- It's important to note that in a vacuum, all electromagnetic waves, including microwaves and optical waves (light), travel at the same speed, which is approximately \(3 \times 10^8\) meters per second. Thus, the reason is also **false**.

**Step 3: Conclusion**
- Since both the assertion and the reason are false, the correct answer is that both the assertion and reason are false.

**Final Answer:**
The correct option is D: Both assertion and reason are false.
