Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
$H_{2} S$ is less acidic than $H_{2} T e$ .
$T e$ has larger radius than S.
On moving down the oxygen family, the acidic nature of hydride increases due to weak bonds and stability of the conjugate base.

On moving down the oxygen family the size increases due to the addition of a new shell.
