Metallic iron produces only ferrous chloride (FeCl2) on treatment with hydrochloric acid. Hydrogen gas is also liberated as the other product.
Fe +2HCl = FeCl2 + H2
But when iron is heated with chlorine gas, ferric chloride (FeCl3) is formed.
2Fe + 3Cl2 + 2FeCl3
hope you got it

Dear student 
When dilute Hydrochloric acid is added to iron filings, iron chloride & hydrogen gas is produced. The iron displaces hydrogen from hydrochloric acid to form iron (II) chloride & hydrogen gas. This is a single displacement reaction. Thus the answer is option (A) Hydrogen gas and iron chloride are produced.
Good Luck
