Explanation / Answer

1) Benedict's test - The resulting solution will be brick red because more than 2% of reducing sugar will be present. The wafer has high sugar content of 10g out of 31g (serving size).

Iodine test - Blue - black color will be produced in the resulting solution due to the presence of starch (complex carbohydrates), which is 22g of the serving size of 31g.

Biuret test - The resulting solution will be violet due to the presence of protein in the solution. The protein content in the food is 1g out of 31g. The biuret method can be used to detect a range of total protein of 1 to 10 g/dl.
