A) A collision in which linear momentum is also conserved

B) A collision which is perfectly inelastic

C) A collision which is perfectly elastic

D) A collision with a net external torque

D) A collision with a net external torque.

The law of conservation of angular momentum states that when no external torque acts on an object, no change of angular momentum will occur.
