Which of the following is a typical normal blood sugar range?

• A. 60-100 mg/dL
• B. 80-120 mg/dL
• C. 40-60 mg/dL
• D. 100-140 mg/dL

Answer: (B)

Blood glucose in a healthy person stays within a fairly narrow window throughout the day. A typical normal range is about 80-120 mg/dL, which covers fasting values around 70-99 mg/dL and post-meal values that generally stay below 140 mg/dL. Values at the low end, like 60 mg/dL, can signal hypoglycemia, while higher ranges such as 100-140 mg/dL can reflect post-meal peaks or potential dysregulation if they persist. So the 80-120 mg/dL range best represents everyday normal variation.
