Solution
The correct option is A Violet precipitate
Benedict’s Test is used to test for simple carbohydrates. The Benedict’s test identifies reducing sugars (monosaccharides and some disaccharides), which have free ketone or aldehyde functional groups. Benedict’s solution can be used to test for the presence of glucose in urine. When glucose is mixed with Benedict's reagent and heated, a reduction reaction causes the Benedict's reagent to change color. The color varies from green to dark red (brick) or rusty-brown, depending on the amount of and type of sugar. Glucose never gives violet colour precipitate with Benedict's solution.
