Solution

The correct option is A $H_{2}$
The reaction of iron with dilute hydrochloric acid leads to the formation of iron (III) chloride and hydrogen gas ( $H_{2}$ ). It is this $H_{2}$ gas which evolves in the form of bubbles. The reaction involved is as follows:

$2 F e (s) + 6 H C l (a q) \to 2 F e C l_{3} (s) + 3 H_{2} (g)$
