(C) In scientific notation, every number is expressed as $a 	imes 10^{b}$, where $a$ is a number between $1$ and $10$, and $b$ is any positive or negative integer exponent.Significant figures are determined only by the digits in the coefficient $a$.The power of $10$ (i.e.,$10^{22}$) is irrelevant to the determination of significant figures.In the given value $3.78 	imes 10^{22}$, the coefficient is $3.78$.Since all non-zero digits are significant, the number of significant figures in $3.78$ is $3$.

List-$I$ (Number)	List-$II$ (Significant figures)
$A. 1001$	$I. 3$
$B. 010.1$	$II. 4$
$C. 100.100$	$III. 5$
$D. 0.0010010$	$IV. 6$

The number of significant figures in $3.78 \times 10^{22} \ kg$ is
