let us take a container containing air in it. we increase the pressure on air in the container at the east end . the pressure is transmitted in

A . West direction

B. North direction

C. South direction

D. Equally in all directions

The pressure at any point is equal in all directions , it is a basic law of hydrodynamics. So whenever we introduce some extra pressure inside a fluid (air in present case) at any point it will always be distributed equally in all the directions.

So (D) Is the correct option.
