The slope of the graph gives the angular acceleration which is the rotational equivalent of tangential acceleration.

Recall, the formula for calculating net torque is expressed as

T = Ia

where

I represents rotational inertia

a represents angular acceleration

Given that I = 0.125

then, the correct option is

Yes because the slope of the graph multiplied by the rotational inertia is equal to the net torque on the edge of the disk
