Quizplus · Accepted Answer

The measurement is given to the tenths place (87.2), and there are no other digits provided, so we can assume this is the limit of the equipment's precision. Adding more zeros after the hundredths place (as in D and E) implies a higher degree of precision than actually given by the measurement, so C is the best choice. A is not precise enough and does not match the tenths place given.
