Answer: Option (c) is the correct answer.
Explanation:
A reaction in which two or more molecules combine together to result in the formation of a larger molecules then this type of reactions are known as addition reactions.
Usually compounds which contain a double bond undergo addition reactions.
For example, a compound with carbon-carbon double bond, carbonyl group, imine group etc undergo addition reaction.
Thus, we can conclude that in an addition reaction, carbon carbon double bond of the reactant is broken.
