C. substitution

The type of reaction that is peculiar to benzene is C. substitution. Benzene is known for its unique aromaticity, which means it undergoes substitution reactions rather than addition reactions. In substitution reactions, one or more hydrogen atoms in benzene are replaced by other atoms or groups, while the carbon skeleton remains intact.
