Best answer
Correct answer is (d) Ethyl alcohol

The best explanation: Ethyl alcohol is drinkable and is made unfit to drink to avoid misuse in industries. This is done by adding some methanol, copper sulphate (to give it colour) and pyridine (to make it foul smelling). This is known as denaturation of alcohol.
