D:
Correct Answer
C
Explanation
Fe (Iron): Iron reacts with dilute HCl to produce iron(II) chloride (FeCl₂) and hydrogen gas (H₂).
Sn (Tin): Tin also reacts with dilute HCl to produce tin(II) chloride (SnCl₂) and hydrogen gas.
Cu (Copper) and Mg (Magnesium): These metals are less reactive than iron and tin and do not readily dissolve in dilute HCl at room temperature. However, magnesium will react with hotter dilute HCl to produce magnesium chloride (MgCl₂) and hydrogen gas.
Therefore, the correct answer is Mg, Sn and Fe.
