Explanation: 

Detailed explanation-1: -Vegetables and vanaspati are made from vegetable oils using hydrogen gas. It’s added to oils to make products more solid or spreadable because it’s a translucent, odourless, tasteless, combustible gaseous material. As a result, hydrogen gas is employed in the production of vegetable oil and vanaspati.

Detailed explanation-2: -Detailed Solution. The correct answer is Hydrogen. In the manufacture of Vanaspati ghee from vegetable oils, Hydrogen (H2) gas is used. Bypassing hydrogen gas, Vegetable Oil’s unsaturated fatty acids are converted into saturated fatty acids to form vanaspati ghee.

Detailed explanation-3: -So the above statement “Vanaspati ghee is obtained by the hydrogenation of vegetable oil” is true.

Detailed explanation-4: -The correct answer is Hydrogen. The gas used in the manufacture of Vanaspati Ghee from Vanaspati Oil is Hydrogen. At high pressure, in the presence of nickel catalyst, hydrogen is mixed with vegetable oils which turn them into vegetable ghee. This process is called the hydrogenation of oils.
