Metal reacts with acid to produce hydrogen gas. But when metal reacts with $H N O_{3}$ hydrogen gas is not given out. Give a reason.

X = C

Y = N a

Z = B r

	Hydride of X	Hydride of Y	Hydride of Z
(A)	Colourless gas insoluble in $H_{2}$	Silver/grey solid, reacts with $H_{2} O$ to form an alkaline solution	Colourless gas form a strong acid in $H_{2} O$
(B)	Colourless liquid, no reaction with $H_{2} O$	Silver/grey solid, forms $H_{2} O$	Ionic solid with formula $Z H$
(C)	Colourless gas found naturally	Does not conduct electricity in the molten state	Colourless gas, reacts with $C l_{2}$
(D)	Non-polar compound reacts with $C l_{2}$ in light	Silver/grey ionic solid with formula $Y H_{2}$	Forms when water is added to phosphorus and element Z
