Best answer
The correct answer is (d) Molasses

Best explanation: Molasses is a by-product of the sugar industry. After testing for its applications, molasses was not found to be protein rich; whereas the Gelatin got from meat, casein made from milk and the glue got from plants is all protein rich.
