Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).\n Assertion (A): For macroscopic objects, the Heisenberg uncertainty principle has no real practical significance.\n Reason (R): The uncertainty in position and velocity calculated for macroscopic objects is extremely small and negligible compared to their dimensions. \nIn 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.
