Answer:

The correct answer is - Benedict's solution for the test for glucose in food.

Explanation:

Benedict's solution is a test that is used to check if there is a presence of glucose in a food sample or not. It is possible due to the oxidation of the aldehyde present in the glucose turns to carboxylic acid in presence of the clear blue solution of sodium and copper salts or benedict's solution.

In presence of Benedict's solution the color of the sample turns yellow to orange with an increase in heat, however, the initial color of the solution is aqua blue.

Thus, the correct answer is - Benedict's solution for the test for glucose in food.
