Could you explain why the answer for this is D? Is it because we can’t assume that the point of intersection is the center of the circle? I initially wrote C for the answer but I think I conflated equal angles for A and B at the point of intersection with equal areas for A and B.

The areas of A and B would be equal if the point of intersection was the center of the circle, is that correct?

Thank you!
