Friction will be always at slipping point of ladder means a horizontal surface. At wall there will be reaction Force Not Friction so.

If any ladder is inclined against roughwall then friction act in both upward of vertical wall as well as towards it.

At the point of vertical rough surface as soon as the ladder descends down the f will act upward tangential.

For a smooth wall no friction because the coefficient of friction is 0.
Hence option C.
Hence option C.

Why B is correct. The upper end is smooth so no friction. The given answer is right.

Wall is smooth given in the question so no friction.

There is no normal reaction at an upper end.
