Which of the following measurements has the greatest precision?

a. 100

b. 100.0

c. 100.00

d. 1

The corresponding measurement that has the greatest precision which can be obtained by a value that possess the greatest number of significant figures would be C. 100.00

This figure has 5 significant figures, it is most precise measurement as we are certain of each value, and that it also has the greatest number of significant figures compared to other values.

I believe the correct answer from the choices listed above is option C. The measurement that has the greatest precision is 100.00. The more significant figures in the measurement means the more precise the measurement is. Hope this answers the question.
