As we have learnt,

Barfoed's test is used to distinguish between Monosaccharide and Disaccharide.

The regent used is cupric acetate in acetic acid and produces a brick red precipitate of copper (I) oxide.

\text{RCHO}+\text{Cu}^{2+}\rightarrow \text{RCOOH}+\text{Cu}_{2}\text{O}

Hence, the correct answer is option (3)
