### VSEPR Theory and Molecular Geometry

**Question:**
In VSEPR theory, molecular geometry is determined by _______ 

**Options:**
- O electron-nucleus attractive forces.
- O proton-proton repulsive forces.
- O electron-electron repulsive forces.
- O electron-electron attractive forces.
- O electron-proton attractive forces.

**Explanation:**
In VSEPR (Valence Shell Electron Pair Repulsion) theory, the shape of a molecule is determined by the repulsive interactions between electron pairs in the valence shell of the central atom. These electron pairs can include bonding pairs, which are shared with other atoms, and lone pairs, which are not shared.

The correct answer to the question is:
- **O electron-electron repulsive forces.**

These repulsive forces cause the electron pairs to arrange themselves as far apart as possible in three-dimensional space to minimize repulsion, thus determining the geometry of the molecule.
