(D) Glyceraldehyde is an aldotriose with the formula $HOCH_2-CH(OH)-CHO$. In a Fischer projection,the $D$-configuration is assigned when the hydroxyl group $(-OH)$ on the chiral carbon atom is on the right side when the carbon chain is written vertically with the most oxidized carbon $(CHO)$ at the top. Option $D$ shows the $CHO$ group at the bottom,but by rotating the molecule or re-orienting the Fischer projection,we can see that the $-OH$ group is on the right side relative to the carbon chain. Specifically,in option $D$,the $CHO$ is at the bottom and $CH_2OH$ is at the top. If we rotate the molecule by $180^{\circ}$ in the plane of the paper,the $CHO$ moves to the top and $CH_2OH$ moves to the bottom,placing the $-OH$ group on the right,which corresponds to $D$-glyceraldehyde.
