Question Analysis
This question involves VSEPR theory and the concept of electron domains.

Key Concept Explanation
An electron domain (also called an electron group) refers to any area around the central atom where electrons are concentrated. Electron domains include both bonding pairs and non-bonding (lone) pairs of electrons. For bonding pairs, single, double, and triple bonds all count as one electron domain.

Step-by-step Solution
1. Identify the central atom: Sulfur (S).
2. Determine valence electrons: Sulfur has 6 valence electrons.
3. Analyze the central atom: It forms two S–H bonds → 2 bonding domains. The remaining electrons form ...
