question: Q:A 53-year-old woman presents for a follow-up. She took some blood tests recently for her yearly physical, and her random blood sugar level was found to be 251 mg/dL. She was asked to repeat her blood sugar and come back with the new reports. At that time, her fasting blood sugar level was 130 mg/dL and the postprandial glucose level was 245 mg/dL. Her HbA1c is 8.9%. She has had occasions where she felt light-headed and felt better only after she had something to eat. Her physician starts her on a drug to help her control her sugar levels. He also advised that she should get her liver enzymes checked with a repeat HbA1c in 3 months. Which of the following is the mechanism of action of the drug that she was most likely prescribed?? 
  {'A': 'Stimulates the release of insulin from the pancreas.', 'B': 'Increases the uptake of glucose and reduces peripheral insulin resistance.', 'C': 'Acts as an agonist at the peroxisome proliferator-activated receptor-Ƴ.', 'D': 'Inhibit alpha-glucosidase in the intestines.', 'E': 'Decreases the secretion of glucagon.'},
