Answer»

option (d) is correct.

why pressure is not a vector

We can put the walls of our container anywhere inside the gas, and the force per unit area (thepressure) is the same. ... Therefore,pressure is a scalar quantity, not avector quantity. It has magnitude but no direction sense associated with it.Pressureforce acts in all directions at a point inside a gas.
