Correct Answer: Option D
Explanation:
Hydrogen sulphide reduces a brownish.yellow sptution ef iron(III) chloride to a green solution of iron(II) chloride. The hydrogen sulphide itself is oxidized to sulphurand hydroge chloride. Iron(III) to iron(II) is gain of electron, the process is reduction i.e. \(Fe ^{3+}\) is reduced to \(Fe ^{2+}\)
