HEY MATE!!!!!
The answer is second option:- a1=2a2
This is because during the motion the 4 kg block will move downward opening the Rope of the movable pulley from both sides from the upper side as well as lower side which will cause the 8 kg mass to move with acceleration A1 but since the rope is opening two times of the movable Pulley's displacement the 4 kg mass will move from two times as the acceleration of A1 which is 2a2
