Solution

The correct option is C Assertion is incorrect but Reason is correct
The assertion is incorrect because force exerted by the fluid is a result of inter molecular collisions also and also due to particles colliding with surroundings.
The reason is correct because pressure is defined as normal (perpendicular) force upon unit area exerted by particles on container walls.So pressure is a result of normal force exerted by particles collision.
