C Correct answer
Explanation

Normal fasting blood sugar levels are typically 80-90 mg/dL (not mg/ml as written - this appears to be a unit error in the question). Post-meal levels can rise to around 140 mg/dL. Levels above 126 mg/dL (fasting) may indicate diabetes. Option C is correct in numerical value despite the unit inconsistency.
