Glyceraldehyde is an aldose monosaccharide. The Fischer projection of D-glyceraldehyde is given below. Draw D-glyceraldehyde using wedge and dash bonds around the chirality center and including ALL hydrogen atoms.

Image is not given in the question, so the image for the question is given below.

Fischer projection is a two-dimensional representation of a three-dimensional organic molecule by projection.

Wedge and dash bonds are used to represent the three-dimensional structure of a molecule, in which wedges indicates bonds towards the viewer, solid lines indicates bonds in the plane of the image and dashed lines indicates bonds away from the viewer.

Wedge and dash bonds structure of D-glyceraldehyde is attached below.
