A Correct answer
Explanation

Hydrogenation is the correct process for converting liquid cooking oils into solid vegetable ghee (vanaspati). During hydrogenation, hydrogen gas is bubbled through the oil in the presence of a nickel catalyst, adding hydrogen to the double bonds in unsaturated fatty acids, which increases the melting point and makes the oil solid at room temperature.
