Final answer:
A fasting plasma glucose test result of 120 mg/dL indicates a prediabetic level. Hence the correct answer is option B
Step-by-step explanation:
A fasting plasma glucose test result of 120 mg/dL indicates a prediabetic level. Diabetes is diagnosed in people who have abnormally high levels of blood glucose after fasting for at least 12 hours. A fasting blood glucose level between 100 and 125 mg/dL is considered prediabetic, while a level higher than 125 mg/dL is considered diabetic.
Hence the correct answer is option B
