Explanation:

The following reaction takes place

2HCl (aq) + Fe (s) → FeCl₂ (aq) + H₂ (g)

So, when dilute hydrochloric acid(HCl) is added to iron fillings(Fe) then iron chloride(FeCl₂) and hydrogen gas(H₂) are produced

Final Answer:

Option A is correct i.e : Hydrogen gas and iron chloride are produced
