Tangent keys are actually a pair. These pair of keys are placed right angles to each other and tangent to the surface of the shaft. Each key will withstand the torsion in one direction only.

D is the right answer. I agree.

Tangent key withstands torsion in one direction only that's why two tangent keys are used opposite when the shaft is subjected to high impact torque.

Tangent key allows one side rotation only.

I agree with you @Fayaz.

I think tangent key is the wrong answer, because a tangent key acts on single direction only.
