Question Analysis
This question involves VSEPR theory and applying it to a molecule with multiple atoms to determine the local geometry around a specific central atom. 

Key Concept Explanation
According to VSEPR theory, electron pairs around a central atom repel each other and arrange themselves as far apart as possible to minimize repulsion.
The molecular geometry depends on: 1. The number of electron domains (bonding + lone pairs). 2. Whether lone pairs are present.

Step-by-step Solution
1. Structure analysis: 
Carbon forms 3 single bonds with hydrogen atoms and 1 single bond with a nitrogen atom (4 bonding electron domains).
Carbon has no lone pairs (0 non-bonding electron domains).
2. Total electron domains aroun...
