Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): When a solid sphere is submerged in a fluid under uniform high pressure, it undergoes hydraulic compression without any change in its geometrical shape. Reason (R): The hydraulic pressure exerted by the fluid acts in perpendicular direction at each point of the sphere's surface, leading exclusively to volume strain. In the light of the above statements, choose the correct answer from the options given below:

1. A
   Both (A) and (R) are true and (R) is the correct explanation of (A).
2. B
   Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
3. C
   (A) is true but (R) is false.
4. D
   (A) is false but (R) is true.
