Verified step by step guidance

Understand the process of hydrogenation: Hydrogenation is a chemical reaction that involves the addition of hydrogen (H₂) to unsaturated bonds, typically carbon-carbon double bonds, in organic compounds.

Identify the structure of unsaturated fatty acids: Unsaturated fatty acids contain one or more double bonds between carbon atoms in their hydrocarbon chains. These double bonds can be converted to single bonds through hydrogenation.

Recognize the goal of hydrogenation in vegetable oils: The primary purpose of hydrogenation in vegetable oils is to make them more solid or semisolid at room temperature, which is achieved by converting double bonds to single bonds.

Examine the options provided: The correct process involves adding hydrogen atoms to the single-bonded carbon atoms of the fatty acid hydrocarbon chains, thereby converting carbon-carbon double bonds to single bonds.

Conclude with the correct answer: The correct answer is 'adding hydrogen atoms to the fatty acid hydrocarbon chains, thereby converting carbon-carbon double bonds to single bonds.' This process increases the saturation of the fatty acids, making the oil more solid.
