Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Sound travels faster in solids than gases. It is because the elasticity of solid is more than that of gases. Solids posses greater density than gases. Though density has effect on the velocity of sound in the medium as follows :

$\Rightarrow v \propto \frac{1}{\sqrt{p}}$
In case of solid, its elasticity far exceeds that of gas so its effect far exceeds the effect of density.
