(C) -Glyceraldehyde is represented in a Fischer projection with the $CHO$ group at the top,the $CH_2OH$ group at the bottom,and the $OH$ group on the right side of the chiral carbon.By rotating the Fischer projection by $180^{\circ}$ in the plane of the paper,the configuration remains unchanged.Option $(C)$ shows the structure with $CHO$ at the top,$OH$ on the left,$CH_2OH$ on the right,and $H$ at the bottom. If we rotate this structure by $90^{\circ}$ clockwise,it does not represent the same molecule. However,if we perform two swaps (which preserves configuration),we can transform the structure in $(C)$ to the standard $D$-Glyceraldehyde representation. Specifically,swapping $OH$ with $CH_2OH$ and then $OH$ with $H$ (or similar valid operations) confirms that the spatial arrangement of the groups around the chiral center in $(C)$ is equivalent to $D$-Glyceraldehyde.

Which of the following Fischer projection formulas is the same as $D$-Glyceraldehyde?
