What is the normal fasting blood glucose range listed?

• A. 80-120 mg/dL
• B. 70-110 mg/dL
• C. 90-140 mg/dL
• D. 60-100 mg/dL

Answer: (A)

Fasting blood glucose is the baseline level after an overnight fast, used to judge how well the body regulates glucose and insulin. In this material, the normal range is a middle-ground window that is wide enough to account for small biological and lab variations, yet narrow enough to stay clear of values that would indicate impaired glucose tolerance or diabetes. Values well below this window could raise concern for hypoglycemia, while values above it suggest possible prediabetes or diabetes. The other options fall outside this practical normal window—either too low or too high for a healthy fasting state—so the chosen range best fits the standard described in this context.
