Explanation

we are told that the two given shaded areas are equal however no more information is given. We cannot assume that the two chords drawn on the circle pass through the center of the circle and form the diameter. If that was the case A and B would be equal but without that information we cannot for certain conclude that the two areas are equal option D

correct: D It might be deduced that the two crossing lines are diameters. But it is possible that we draw lines upper or lower, in every part of the circle, to make equal spaces. so without no more information, we can't deduce that lines are diameters and the unshaded parts are equal or not. _________________
