(a)
Interpretation:
The given measurement is to be added and the answer is rounded off to the proper significant digit.
Concept introduction:
During the addition or subtraction of measurements, the answer is found to be limited by the value with the greatest uncertainty that is the answer by the decimal place is limited. The final unit in addition and subtraction remains the same as the unit in each single data.
