What Does the Exponential Term in an Exponential Expression Tell

What does the exponential term in an exponential expression tell us about the number of significant figures?

A) The exponential term has no information about the number of significant digits in an exponential expression.
B) The number in the exponential term indicates how many zeros must be added to the number of significant figures in the significand.
C) The number in the exponential term must be added to the number of significant figures in the significand.
D) The number of significant figures in the significand must be multiplied by the number in the exponential term.
