When the bus is moving in one direction, the bodies of the passengers are aligned to moving in that direction. When the bus suddenly takes a turn, the bodies will not be able to adjust to the sudden turn immediately. So, the upper part of the body will still be moving in forward direction, while the lower part goes along with the bus(as it is in contact with the bus, it will move along with it). This inability of an object to align to sudden changes in motion is called as inertia of motion. So, the bodies will fall to other side due to inertia of motion. Hence, Option (A)
