Solution

The correct option is B False
Pressure is the force applied perpendicular to the surface of an object.
Pressure depends on the contact area of the body.
There is different contact area in case of standing and lying.
So, Raghav exerts different pressure on the ground whether he is standing or he is lying.
Hence, the given statement is false.
