Methane is a colorless gas insoluble in water.
Sodium hydride is a silver/grey solid. It reacts with water to form an alkaline solution of sodium hydroxide.
Hydrogen bromide is a colorless gas which forms hydrobromic acid - a strong acid in water.

	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
