Question Analysis:  
This question assesses the understanding of interior angles in regular polygons, specifically a hexagon.
The focus is on correctly applying the formula for calculating the measure of each interior angle.  

Key Concept Explanation:  
For any regular polygon with sides, each interior angle can be calculated using the formula:  
 
This formula derives from dividing the sum of all interior angles by the number of sides.  

Step-by-Step Solution:  
First, identify the number of sides in a hexagon: .  
Next, substitute into the formula:
