# When $SiO_2$ is beated with C in an electric formula

$\begin{array}{1 1}(a)\;Silica\;is\;obtained\\(b)\;Carbide\;is\;obtained\\(c)\;Carborundum\;is\;obtained\\(d)\;Calcium\;silicate\;is\;obtained\end{array}$

$SiO_2+SC\rightarrow SiC+2CO$
$SiC\Rightarrow$ carborundum
Hence Carborundum is obtained.
Hence (c) is the correct answer.
