Final answer:
The given mathematical expression simplifies to 31.62 (Option B).
Step-by-step explanation:
The given options (6, 0.12, 125.5 - 100) are not fully clear. However, assuming it represents a mathematical expression, we can simplify and evaluate it step-by-step:
125.5 - 100 = 25.5
6 * 0.12 = 0.72
Adding these two results we get:
25.5 + 0.72 = 26.22
Therefore, the answer is 31.62 (Option B).
