Solution
The correct option is B Copper sulphate
In order to identify the presence of protein in food, we add copper sulphate solution to a test tube containing a mixture of food and water. After a few seconds, we add caustic soda. If the colour of the solution changes to violet, then it indicates the presence of protein.
