Which of the following is considered a normal range for glucose levels in the body?

The normal range for glucose levels in the body is generally accepted to be between 60 and 100 mg/dL for individuals who are fasting. This range indicates that the body is maintaining proper glucose metabolism, which is vital for energy production and overall health. Values below this range may suggest hypoglycemia, while values above this range could indicate hyperglycemia, which may be a sign of insulin resistance or diabetes. The other options reflect broader or different ranges that may not accurately represent the standard fasting glucose levels typically recognized in clinical practice.
