(3) C is correct answer
Explanation:
Given statement : A non-uniform sphere with four dots A, B, C and D representing location of center of mass residing on rough inclined plane.
If sphere is in equilibrium state then net torque applied at the point of of contact will be zero.
For that respective line of action, mg needs to be passed through point of contact.
Thus, At C position, sphere is in equilibrium state.
