ASSERTION.
A body on an inclined plane just tends to slide down if the angle of inclination is equal to the angle of friction.
REASON.
When the angle of inclination is equal to the angle of friction, the component of weight parallel to the plane is just sufficient to overcome the frictional force.
So, A is the answer.

Option C is right as here question is not asking about the limiting case but questions says when body begins to move i.e. more important,
And hence it can be possible only when (angle of inclination > angle of friction) otherwise on equal to case body will not move it still will be on rest.

Since the body BEGINS to move, i.e. within Limiting friction, hence the angle of friction is equal to angle of repose.
Hence Option A is correct.
Hence Option A is correct.

Body will begin to move down the plan when the angle of inclination of the plan is EQUAL to the angle of friction.
So, the Answer is A.
So, the Answer is A.

If the body just move down the plane.
It should be angle of repose and angle of friction should be equal.
Hence option A is right.
It should be angle of repose and angle of friction should be equal.
Hence option A is right.
