Which of the following has the smallest number of significant figures? Why?
A. All of the other options have the same number of significant figures.
B. 0.0050
C. 0.0500
D. 0.0005
E. 0.5000

Significant figures are defined as numbers that carry a meaningful notation to any measurement.
A. The first options is false as all other options have a difference in the number of significant figures.
B. 0.0050 has 2 significant figures as the zeroes before the decimal and after the decimal and before a non-zero digit are non-significant, whereas the zero after the non-zero digit after the decimal is considered significant.
C. 0.0500 has 3 significant figures, as the zeroes before the decimal and after the decimal and before a non-zero digit are non-significant, whereas the zero after the non-zero digit after the decimal is considered significant.
