(B) Epimers are diastereomers that differ in configuration at only one stereogenic center.In the given structures,the first molecule is $D$-glucose and the second molecule is $D$-galactose.Numbering the carbon atoms starting from the aldehyde group $(CHO)$ as $C-1$:$C-1$: $CHO$$C-2$: $-OH$ on right$C-3$: $-OH$ on right$C-4$: $-OH$ on right (in glucose) vs $-OH$ on left (in galactose)$C-5$: $-OH$ on right$C-6$: $CH_2OH$Since the configuration differs only at the $C-4$ position,they are $C-4$ epimers.Therefore,$n = 4$.

The given structures are $C_n$ epimers. What is $n$?
