Answer : Option B

Explanation :

Here, the given choices are not closer. Hence, we can make a fair amount of approximation
in the calculations.

$MF#%\begin{align}&\dfrac{729.124932 \times 0.04293 \times 2.9233376}{0.0683 \times 97.671 \times 999.6289}\\\\
&\approx \dfrac{730 \times 0.05 \times 3}{0.05 \times 100 \times 1000}
\approx \dfrac{730 \times 3}{100 \times 1000}
\approx \dfrac{73 \times 3}{10 \times 1000}\\\\
&\approx \dfrac{219}{10 \times 1000}
\approx .0219\\\\
&\approx .03\end{align} $MF#%
