Step 1: Role of hydrogen in Vanaspati Ghee production.
Vanaspati Ghee is produced via hydrogenation, a process where hydrogen gas is introduced into liquid vegetable oils with a nickel catalyst. This reaction saturates fatty acids, transforming the oil into a semi-solid state.Step 2: Evaluation of alternative options.
Option (A): Olive oil. Incorrect. Olive oil remains liquid and is not hydrogenated. Option (B): Ghee. Incorrect. Ghee is derived from animal milk fat, not by hydrogenation. Option (C): Coconut oil. Incorrect. Coconut oil is naturally saturated and does not undergo hydrogenation.Step 3: Final determination.
Hydrogen plays a crucial role in the hydrogenation process for Vanaspati Ghee.\[\therefore \text{The correct answer is: Vanaspati Ghee.}\]
