Assertion: The driver in a vechicle moving with a constant speed on a straight road is in a non-inertial frame of referance.
Reason: A reference frame in which Newton's laws of motion are applicable is non-inertial.

Options

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

Explanation

To solve the question regarding the assertion and reason provided, we will analyze each statement step by step.

### Step 1: Analyze the Assertion
The assertion states: "The driver in a vehicle moving with a constant speed on a straight road is in a non-inertial frame of reference."

- A vehicle moving with a constant speed in a straight line is considered to be in an inertial frame of reference. In an inertial frame, Newton's laws of motion hold true.
- Since the driver experiences no acceleration (the speed is constant and the direction is straight), the frame of reference is inertial.

**Conclusion for Step 1**: The assertion is false.

### Step 2: Analyze the Reason
The reason states: "A reference frame in which Newton's laws of motion are applicable is non-inertial."

- This statement is incorrect. A reference frame in which Newton's laws of motion are applicable is actually an inertial frame of reference. Non-inertial frames are those in which Newton's laws do not hold without the introduction of fictitious forces (like in accelerating or rotating frames).

**Conclusion for Step 2**: The reason is also false.

### Final Conclusion
Both the assertion and the reason are false. The assertion incorrectly identifies the frame of reference of the driver, and the reason misstates the conditions under which Newton's laws apply.

### Summary
- Assertion: False
- Reason: False
