Solution

The correct option is A Chlorine
When chlorine reacts with iron(II) ions in solution, chloride ions and iron(III) ions are produced.
Ionic equation:
$C l_{2} (g) + 2 F e^{2 +} (a q) \to 2 C l^{-} (a q) + 2 F e^{3 +} (a q)$
The equation shows that the $F e^{2 +}$ ions have formed $F e^{3 +}$ ions, i.e., each ion has lost an electron. This means the $F e^{2 +}$ ions have been oxidised.
