(C) Given the relation $S = \frac{a^{1/2} b}{c^3 d^4}$.To find the maximum relative error in $S$, we use the formula for propagation of errors:$\frac{\Delta S}{S} = \frac{1}{2} \frac{\Delta a}{a} + \frac{\Delta b}{b} + 3 \frac{\Delta c}{c} + 4 \frac{\Delta d}{d}$.Substituting the given percentage errors:$\left( \frac{\Delta S}{S} 	imes 100 ight) = \frac{1}{2} 	imes (2 \%) + (1 \%) + 3 	imes (1 \%) + 4 	imes (1 \%)$.Calculating the values:$= 1 \% + 1 \% + 3 \% + 4 \% = 9 \%$.Therefore, the percentage error in $S$ is $9 \%$.

$A$ physical quantity $S$ is related to four observables $a, b, c$, and $d$ as $S = \frac{\sqrt{a} b}{c^3 d^4}$. If the percentage errors of measurement in $a, b, c$, and $d$ are $2 \%$, $1 \%$, $1 \%$, and $1 \%$ respectively, then the percentage error in the quantity $S$ is: (in $\%$)
