**Title:** Redrawing a 3D Molecule as a Fischer Projection

**Objective:** Learn how to translate a three-dimensional molecular structure into a two-dimensional Fischer projection.

**Description:**

In this exercise, we are tasked with converting the given stereochemical molecule diagram into its corresponding Fischer projection. The original structure is a tetrahedral molecule with the formula C2H5BrCl. 

**Molecular Diagram:** 

- The molecule consists of two methyl groups (CH3), a bromine (Br), and a chlorine (Cl) atom arranged around a central carbon atom.
- The bromine (Br) is drawn as a wedge, indicating it projects above the plane of the paper.
- The chlorine (Cl) is indicated with hashing, suggesting it extends below the plane of the paper.
- There are two hydrogen atoms (H) positioned on the remaining sides.

**Fischer Projection Options:**

Below the diagram, five choices (A-E) are provided, each representing a possible Fischer projection of the molecule.

- **Option A:** Vertical axis: CH3 at both ends, horizontal axis: H and Cl on the left, Br and H on the right.
- **Option B:** Vertical axis: CH3 at both ends, horizontal axis: Br and Cl on the left, H and H on the right.
- **Option C:** Vertical axis: CH3 at both ends, horizontal axis: H and Br on the left, Cl and H on the right.
- **Option D:** Vertical axis: CH3 at both ends, horizontal axis: Br and H on the left, H and Cl on the right.
- **Option E:** Vertical axis: CH3 at both ends, horizontal axis: Br and Cl on the left, H and H on the right.

**Conclusion:** 

The task is to correctly translate the three-dimensional tetrahedral structure into one of the two-dimensional Fischer projections provided, ensuring that the stereochemistry is accurately represented.
