(a)
Interpretation:
The given measurement is to be multiplied and the answer is rounded off to the proper significant digit.
Concept introduction:
In the multiplication or division of measurements, the answer is found to be limited by the measurement value with the lowest number of significant digits. The final unit in multiplication is the product of the units of each data.
