Quizplus · Accepted Answer

The center of mass of an explosion is the point where the mass of the explosion is evenly distributed. In this case, the explosion appears symmetrical around point C, which indicates that it is the center of mass. Points A, B, D, and E do not appear to be equidistant from all parts of the explosion and are thus not the center of mass.
