B. `NH_(3),N_(2)H_(4)`
C. `AsH_(3),As_(2)H_(4)`
D. `NH_(3),NH_(4)Cl`

Correct Answer - B
Out of all the hydrides of group 15 elements only `NH_(3)` and `PH_(3)` are basic. Further boiling ppt. of `NH_(3)`is higher than `PH_(3)` and it is distinctly basic whereas `PH_(3)` is weakly basic. Hence X is `NH_(3)`
