The correct option is C
Apparent frequency can be calculated as,
$f^{\prime}=f_{0}\left(\frac{v \pm v_{0}}{v \pm v_{s}}\right)$
$\mathrm{f}^{\prime}=\mathrm{f}_{0}\left(\frac{\mathrm{v}+\mathrm{v}_{0}}{\mathrm{v}+\mathrm{v}_{\mathrm{s}}}\right)$
$=1392\left(\frac{343+10}{343+5}\right)$
$=1412 \mathrm{HZ}$
