Solution

The correct option is C τ=dLdt
The relationship between the net external torque and the angular acceleration is of the same form as Newton's second law and is sometimes called Newton's second law for rotation.
It is not as general a relationship as the linear one because the moment of inertia is not strictly quantity.
So, τ=dLdt
Hence,
option (C) is correct answer.
