Assertion: If an object is submerged in fluid at rest, the fluid exerts a force on its surface.
Reason: The force exerted by the fluid at rest has to be parallel to the surface in contact with it.

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reason are true but reason is not the correct explanation of assertion.

C

If assertion is true and reason is false.

D

If both assertion and reason are false.
