Assertion $(A):$ $H_2Te$ is more acidic than $H_2S$.
Reason $(R):$ The bond dissociation enthalpy of $H_2Te$ is less than that of $H_2S$.
In the context of the above statements,choose the correct answer from the following options:

• A
  Both $(A)$ and $(R)$ are true,but $(R)$ is not the correct explanation of $(A).$
• B
  Both $(A)$ and $(R)$ are true,and $(R)$ is the correct explanation of $(A).$
• C
  $(A)$ is false,but $(R)$ is true.
• D
