Step-by-step solution
Dalda (Vanaspati) is made by hydrogenating vegetable oils, which are primarily unsaturated triglycerides like triolein. Hydrogenation converts liquid oils into semi-solid fats. Options B, C, and D are incorrect because hydrogenation of soap is not relevant, tristearine is already saturated, and electrolysis of potassium acetate yields alkanes, not fats.
