A

`(X)` turns red litmus blue and produces dense white fumes in contact with dilute `HCl`

B

`(X)` turns filter paper moistened with mercurous nitrate black and gives intense blue coloured solution with `CuSO_(4)(aq)`

The correct Answer is:
D
`NH_(4)^(+)+OH^(-)overset(Delta)toNH_(3)uarr+H_(2)O`
(A)`NH_(3)`,alkaline in nature turns red litmus blue,
`NH_(3)+HCl to NH_(4)Cl` (white fumes)
(B) `2HgNO_(3)+2NH_(3)toubrace(Hg(NH_(2))NO_(3)+Hg)_("black")+NH_(4)NO_(3),CuSO_(4)+4NH_(3)to[Cu(NH_(3))_(4)]SO_(4)` (intense blue)
( C)`2K_(2)(HgI_(4))+NH_(3)+3KOHtoHgOHgNH_(2)I darr("brown")+7KI+2H_(2)O`
