D Correct answer
Explanation

Nickel (Ni) is used as a catalyst in the hydrogenation of vanaspati oil to convert it into vanaspati ghee. This process adds hydrogen to the double bonds in unsaturated fatty acids, making them more saturated and solid at room temperature. Nickel provides an effective catalytic surface for hydrogen addition under moderate temperature and pressure conditions.
