# The correct sequence is : For -Acidic Nature

$\begin{array}{1 1}(a)\;H_2S < H_2Se < H_2Te\\(b)\;H_2Te < H_2S < H_2Se\\(c)\;H_2Te=H_2S < H_2Se\\(d)\;H_2Te=H_2S=H_2Se\end{array}$

Due to decrease in bond dissociation enthalpy down the group,acidic character increases
$H_2S < H_2Se < H_2Te$
Hence (a) is the correct answer.
