Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Both assertion and reason are correct.
$\to$ Mechanical waves can only be produced in solids not in liquid or gas since they do not posses elasticity and inertia.
$\to$ Every wave requires an initial energy input.

But the reason does not explain for assertion.

$∴$ Option (B) is correct.
