Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Acceleration is the rate of change of the velocity of an object with respect to time. And its direction is the same as the direction of change in the velocity vector because both are vector quantities. So the reason is correct.
The assertion is correct because acceleration need not affect the direction of velocity, but acceleration will change its direction (because acceleration is the change in velocity vector, be its magnitude or direction)
But the reason is not the explanation for the assertion.
So the option 'B' is correct.
