B. `H_(2)Se lt H_(2)S lt H_(2)Te`
C. `H_(2)Te lt H_(2)S lt H_(2)Se`
D. `H_(2)Se lt H_(2)Te lt H_(2)S`

Explanation

While comparing element in the same group of the periodic table `H-A` bond strength is a predominatnt facrtor in determining the acidic strenght than its polar nature. As the size of A(Group`16` element ) increase on moving down the group `H-A` bond strength decreases and so the acid strength increases.
