The Correct Option is C

Solution and Explanation

Ceric ammonium nitrate, \((\mathrm{NH_4})_2[\mathrm{Ce(NO_3)_6}]\), is a yellow reagent that forms a red-coloured complex with alcohols, so it identifies the alcohol group.
\(\mathrm{CHCl_3}\)/alc. KOH is the carbylamine (isocyanide) test: primary amines give a foul-smelling isocyanide, so it identifies the amine group.
The order is alcohol, amine.
Answer: (3) alcohol, amine
