The right answer is enzymes (catalase).
Catalase is an enzyme that allows the dismutation of hydrogen peroxide (hydrogen peroxide) in water and oxygen.
The oxygen-oxygen bond of the hydrogen peroxide is cut off by the iron atom of the heme group, creating a molecule of water and a highly oxidizing iron-oxygen bond. This can oxidize a new molecule of hydrogen peroxide, giving oxygen. The enzymatic reaction at play is one of the fastest known.
Within the cell, catalase helps protect the body from the oxidative and harmful action of hydrogen peroxide.

Answer:
Biuret reagent is the correct answer.
Explanation:
Biuret reagent is used to test the presence of the protein in a solution.
The biuret solution contains
Biuret reagent is a solution that is blue in color and when it reacts with protein the color gets a change to pink-purple due presence of several peptide bonds and when there is no protein present in the solution the color remains blue.
The biuret reaction takes place when the copper II ions placed in the solution as a cupric sulfate gets reduce to copper I ions due to the presence of peptide bonds and the color change is observed from blue to violet.
The biuret reagent is used to test for proteins. A biuret test, also known as a peptide bond test, is a chemical test used to measure the number of peptide bonds present in an analyte.
Biuret reagent consists of NaOH (sodium hydroxide) and hydrochlorofluorocarbons (sulfate) and potassium sodium tartrate. The tartrate is added to the chelate to stabilize the cupric ions.
When pure, the reagent is a pale blue color. However, when the reagent is mixed with protein, the reaction results in a light purple color. The deep blue/purple color is caused by a copper ion complex with a protein amide group.
