(D) The reaction of sodium thiosulphate $(Na_2S_2O_3)$ with moist chlorine $(Cl_2)$ is an oxidation reaction.In the presence of water, $Na_2S_2O_3$ is oxidized to sodium sulphate $(Na_2SO_4)$ and hydrochloric acid $(HCl)$, while sulphur $(S)$ is precipitated as a byproduct.The balanced chemical equation is:$Na_2S_2O_3 + Cl_2 + H_2O \longrightarrow Na_2SO_4 + 2HCl + S$Here, $X$ corresponds to sulphur $(S)$.
