Zinc on reaction with NaOH gives a salt (P) along with a gas (X). (P) on reaction with a gas (V) gives white precipitate (W). Which of the following is correct?

A)  \[(P)\,\,\,is\,\,\,N{{a}_{4}}Zn{{O}_{3}},\,\,\,(Y)\,\,\,is\,\,\,{{H}_{2}}S.\]   

B)      \[(X)\,\,\,is\,\,\,{{H}_{2}},\,\,\,(W)\,\,\,is\,\,\,Zn{{(OH)}_{2}}.\]

C)  \[(P)\,\,\,is\,\,\,N{{a}_{2}}Zn{{O}_{2}},\,\,\,(X)\,\,\,is\,\,\,{{O}_{2}}.\]       

D)  \[(W)\,\,\,is\,\,\,ZnS,\,\,\,(X)\,\,\,is\,\,\,{{H}_{2}}.\]
