Solution

The correct option is A Ethyl alcohol
Shake or crush the food to make it dissolve. Filter or dilute the food and ethanol mix so that you get a clear liquid (a solution of fat in ethanol). Add this to a test tube of water. A white (milk-like) emulsion indicates the presence of fats or oils.
So, the correct option is 'Ethyl alcohol'.
