Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Significant figures in the addition or subtraction should be reported to the same decimal place as the term with the least decimal places. Reason (R): The result of an arithmetic operation cannot be more precise than the least precise measurement involved. In the light of the above statements, choose the correct answer from the options given below:

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