The three elements \( X, Y \) and \( Z \) with electronic configurations shown below all form hydrides:
\( \begin{array}{cc}\text { Element } & \text { Electronic configuration } \\ X & 1 s^{2} 2 s^{2} 2 p^{2} \\ Y & 1 s^{2} 2 s^{2} 2 p^{6} 3 s^{1} \\ Z & 1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{6} 3 d^{10} 4 s^{2} 4 p^{5}\end{array} \)
Which set of properties match correctly with properties of the hydrides of these elements:
Hydride of \( \boldsymbol{X} \quad \) Hydride of \( \boldsymbol{Y} \quad \) Hydride of \( \boldsymbol{Z} \)
(a) Colourless gas insoluble Silver/grey solid reacts Colourless gas forms a in \( \mathrm{H}_{2} \mathrm{O} \) with \( \mathrm{H}_{2} \mathrm{O} \) to form an strong acid in \( \mathrm{H}_{2} \mathrm{O} \) alkali
(b) Colourless liquid, no Silver/grey solid forms Ionic solid with formula reaction with \( \mathrm{H}_{2} \mathrm{O} \quad \mathrm{H}_{2} \) and \( \mathrm{H}_{2} \mathrm{O} \quad Z \mathrm{H} \)
(c) Non-polar compound Silver/grey ionic solid Forms when water is reacts with \( \mathrm{Cl}_{2} \) in light with formula \( \mathrm{YH}_{2} \quad \) added to phosphorus and elemental \( Z \).
(d) Colourless gas which Silver/grey solid which Colourless, corrosive burns with air reacts violently with liquid at STP acids
