Solution

The correct option is C Perpendicular to the outer surface.
Thrust always acts perpendicular to the surface and it acts on all the surfaces that are exposed to the fluid. If there is a body of irregular shape then the thrust due to the liquid pressure acts perpendicular to each small area concerned.
