Solution

The correct option is A (a) $\to$ (s, t); (b) $\to$ (s); (c) $\to$ (q); (d) $\to$ (p); (e) $\to$ (r, s)
Electrolysis of water produces $H_{2} (g)$ and $O_{2} (g)$ . Of these two,
dihydrogen is a well known reducing agent. $L i A l H_{4}$ is a popular reducing agent.
$H C l (g)$ is a polar molecule. Heavy water is used in nuclear reactors.
Atomic hydrogen combines on metal surface in a highly exothermic reaction.
It is also a very powerful reducing agent (much more reducing than $H_{2} (g)$ .
