Solution

The correct option is A $2 K (s) + 2 H_{2} O (l) \to 2 K O H (a q) + H_{2} (g)$
Potassium metal reacts very violently with water producing potassium hydroxide (KOH) and hydrogen gas.
$2 K$ (s) + $2 H_{2} O$ (l) $\to$ $2 K O H (a q)$ + $H_{2}$ $↑$ (g)
This reaction is exothermic and releases enough heat to ignite the resulting hydrogen.
Option A is correct.
