Solution

The correct option is A $M g (s) + 2 H C l (a q) \to {M g C l}_{2} (a q) + H_{2} (g)$
$M g (s) + 2 H C l (a q) \to {M g C l}_{2} (a q) + H_{2} (g)$
This is the reaction of metals with acid which is a single replacement reaction and to generate hydrogen gas. A crackling sound is heard as hydrogen burns.
