Question Analysis
This question tests the student's understanding of molecular geometry and the corresponding bond angles as predicted by VSEPR theory.

Key Concept Explanation
A bond angle is the angle between two adjacent bonding electron domains around a central atom. Bond angles are primarily determined by the number of electron domains around the central atom, and deviations mainly occur when lone pairs are present.
109.5° angle: This specific angle is characteristic of a Tetrahedral geometry. 

Option Analysis
1. We need to find the molecule with a bond angle of ~109.5°, which corresponds to a Tetrahedral shape (AX₄). Therefore, the correct answer ...
