Answer: The correct answer is Option C.
Explanation:
Precision refers to the closeness of two or more measurements to each other.
For Example: If you weigh a given substance five times and you get 3.2 kg each time. Then the measurement is very precise.
Accuracy refers to the closeness of a measured value to a standard or known value.
For Example: If the mass of a substance is 32 kg and one person weighed 31 kg and another person weighed 29 kg. Then, the weight measured by first person is more accurate.
According to the question:
Mass weighed by Mary = 10.00 g
Mass weighed by Tommy = 10 g
As, mass weighed by Mary is reported upto 2 decimal places. Thus, it is more precise.
Hence, the correct answer is Option C.
