A Correct answer
Explanation

Vanpati ghee (vegetable ghee) is produced through hydrogenation of liquid vegetable oils to make them solid at room temperature, similar to butter. Hydrogen gas is bubbled through the oil in the presence of a nickel catalyst, adding hydrogen to unsaturated fatty acid chains. This process increases melting point and shelf life. Carbon dioxide, sulfur dioxide, and nitrogen are not used in this process.
