The correct answer is:
C
Te Correct option is C.
The tension at $A$ will be maximum as $\mathrm{mg}$ is acting opposite to tension and it has to exert that much extra cenripetal force to keep the stone in the circle. And tension is least at $\mathrm{C}$ where part of the centripetal force is compensated by $\mathrm{mg}$. This is depicted in the following diagram.
