Correct Answer: Option D
Explanation

When an alkene reacts with hydrogen in the presence of a catalyst, the reaction is called hydrogenation. 

Hydrogenation is an addition reaction that occurs when hydrogen gas is added to an alkene's double bond in the presence of a metal catalyst. The reaction results in the formation of an alkane, which is a saturated compound. 

The reaction is also known as catalytic hydrogenation because a catalyst is required for it to occur. The catalyst lowers the activation energy of the reactants, which increases the reaction rate.
