Answer:
The correct answer is - C) pH paper + Phenol red.
Explanation:
Iodine is a reagent and indicator that is used to test confirm the presence of the starch in the sample by producing its characteristic blue-black color.
pH paper is an indicator that helps in telling about the pH level of a specific sample or solution by changing its color.
Biuret reagent is used to test for the presence of protein as it identifies peptide bonds in a solution.
Benedict's solution is an indicator that is used to confirm the presence of simple sugar in the solution or sample.
Phenol red solution is used as a pH scale to identifies the pH value of a sample or solution.
Sudan Iv is used to find the lipids and fats in the sample or solution.
