Identify the name of method used for three dimensional representation of molecule as follows.

Step-by-step solution

Fischer projection formula represents three-dimensional molecular structure using intersecting horizontal and vertical lines at chiral centers. Horizontal lines indicate bonds projecting toward the viewer, while vertical lines indicate bonds receding into the plane. The given representation matches this convention exactly, with a central chiral carbon at the intersection point. This distinguishes it from wedge formulas (using solid/dashed wedges), Newman projections (viewing along carbon-carbon bonds), and sawhorse
