(B) In a Fischer projection,the $D/L$ configuration is determined by the position of the $-OH$ group on the chiral carbon atom furthest from the principal functional group (the carbonyl group in aldoses).If the $-OH$ group is on the right side,it is assigned the $D$-configuration.If the $-OH$ group is on the left side,it is assigned the $L$-configuration.Looking at option $B$,the structure is glyceraldehyde derivative (specifically an aldotetrose). The chiral carbon furthest from the $CHO$ group is the one attached to the $CH_2OH$ group. In the structure shown in option $B$,the $-OH$ group on the chiral carbon furthest from the $CHO$ group is on the right side,which corresponds to the $D$-isomer.
