Solution
The correct option is C functional group
Functional groups are specific substituents or moieties within molecules that are responsible for the characteristic chemical reactions of those molecules.
Examples: −OH,−COOH,−COOR etc.
Hence, the atom or the group of atoms by which the characteristic reactions of organic compounds are determined, that atom or group of atoms is called functional group.
