Answer
c ) The ratio of the y-component to the x-component (for the velocity vector) does not change with time, and it is that ratio which determines the angle of the velocity vector as in part (b) and thus the direction of motion for the center of mass of the system. From this , the path of the center-of-mass is a straight line.
