Solution

Solution Steps

Step 1: Understanding the Benedict's Test

The Benedict's test is a chemical test used to detect the presence of reducing sugars. It involves the reduction of a metal ion in the reagent.

Step 2: Identifying the Metal in Benedict's Reagent

Benedict's reagent contains copper(II) sulfate. During the test, the copper(II) ions (\(\text{Cu}^{2+}\)) are reduced to copper(I) oxide (\(\text{Cu}_2\text{O}\)), which forms a red or orange precipitate.

Step 3: Determining the Reduced Metal

Since copper(II) ions are reduced to copper(I) oxide, the metal that is reduced in the Benedict's test is copper.

Final Answer

\(\boxed{\text{b) Copper}}\)
