Verified by Experts

The correct Answer is:
B
White phosphorous + Lime water rarr
Calcium salt of an acid `(A) + Gas (X)`
`2 P_4 + 8 Ca(OH)_2 + 6 H_2 O rarr 3 Ca(H_2 PO_2)_2 + 2 PH_3 (X)`
`(A)` is `H_3 PO_2`, hypophosphorous acid.
`(A)` is monobasic acid.
`2 H_3PO_2 overset (Delta) rarr H_3 PO_4 + PH_3`.
