The answer C is correct, because during meshing of gears the top of tooth touch bottom land above the the clearance.

But to avoid the confusion of total depth, It is The radial distance from the top of a tooth to the bottom of a tooth in a gear without meshing with another.

Right answer is total depth.

Working depth=total depth-clearance.

Clearance is the radial distance between the top of the tooth of the one gear to the bottom of the tooth of another mating gear.

The radial distance from the top of a tooth to the bottom of a tooth in a "meshing gear".

Focus on the word meshing gear. So the correct answer is option C.
