Solution
The correct option is A Object A:
Pressure is inversely proportional to the area of the contact. So, the object having minimum surface area of the base will exert maximum pressure on the floor. Object A touches the floor only at a point, so it has the minimum surface area of contact. Thus, pressure exerted by object A is maximum.
