Answer:
the least pressure will be exerted by the 2nd case i.e., B [according the picture] as pressure is inversely proportional to the area. [ i.e. if the area is increased then the pressure will decrease] as the area covered by the boy in case 2nd is more then any other way therefore, the pressure is least in that case.
and the maximum pressure will be in the 3rd case i.e. C [according to the picture] as the area is less therefore the pressure applied will be more.
* also pressure is directly proportional to the force applied [i.e. if the force is more then the pressure is more]
