Question Analysis
This question involves simplifying a molecular formula to its empirical formula. The main focus is on finding the greatest common divisor (GCD) of the subscripts.

Key Concept Explanation
The empirical formula is the simplest whole-number ratio of atoms in a compound. To simplify, divide all subscripts by their GCD.

Step-by-Step Solution
1. Identify subscripts: 4 (C), 12 (H), 2 (O).
2. Find GCD of 4, 12, 2: The largest common factor is 2.
3. Divide each subscript by 2:
C:
H:
O:
