Assertion: A ladder is more apt to slip, when you are high up on it than when you just begin to climb.

C. If assertion is true but reason is false.

Answer

A

Explanation

When a person is high up on the ladder, than a large torque is produced due to his weight about the point of contact between the ladder and the floor. Whereas when he starts climbing up, the torque is small. Due to this reason, the ladder is more apt to slip, when one is high up on it.
