Vedclass · Answer

(B) The given structure is a six-membered pyranose ring.At the anomeric carbon $(C1)$,the $-OH$ group is in the equatorial (up) position,which identifies it as the $\beta$-anomer.Since the substituent at the anomeric carbon is a hydrogen atom $(-H)$ rather than a hydroxymethyl group $(-CH_2OH)$,it is an aldohexose (specifically $\beta$-$D$-glucopyranose).Therefore,the correct option is $B$.
