IF [I] WILL BE TRANSPARENT ,AS WE KNOW THAT THE MATERIALS WHICH ALLOW LIGHT TO PASS THROUGH THEM ARE CALLED TRANSPARENT SO IF WE CUT OUT A SQUARE TRANSPARENT SHEET FROM A ROLL OF TRANSPARENT ,SURELY THE LIGHT PATCH WILL PASS THROUGH[II]THEN THE [II] MATERIAL SHOULD BE SOMETING WHICH CAN NOT ALLOW LIGHT TO PASS TROUGH IT IT SHOULD BE OPAQUE AND THE LAST SQUARE[III] CAN BE MADE OUT FROM ANY MATERIAL,THUS IT WILL NOT CHANGE THE ANSWER.SO WE CONCLUDE THE CORRECT ANSWER IS C

Here, the answer is C. Displacement is the shortest distance covered by a body. In a circular path, the distance between the initial point (Here=P) and the final point (Here=Q) will give you the displacement. Here, Shortest distance between P and Q is PO + OQ = a + a = 2a Hence, the displacement of the cyclist would be 2a.
