(B) Chlorophyll $a$ $(C_{55}H_{72}O_5N_4Mg)$ is the primary photosynthetic pigment.Its structure consists of a porphyrin head and a phytol tail.The porphyrin head is composed of four pyrrole rings $(I, II, III, IV)$ linked by methine bridges.In chlorophyll $a$,the carbon atom $3$ of pyrrole ring $II$ is attached to a methyl group $(-CH_3)$.In contrast,chlorophyll $b$ has an aldehyde group $(-CHO)$ at the same position.

In a chlorophyll $a$ molecule,which of the following groups is attached to carbon atom $3$ of pyrrole ring $II$?
