Which or the following will most likely happen if the pancreas does not produce sufficient insulin?

C. Blood sugar increases b/c insulin lowers blood sugar when it rises too high

Explanation:

Insulin is highly needed by body to regular sugar levels (primarily to lower it when sugar levels rise up). I remember it like this "in" sulin means this hormones "pushes" the sugar inside the cells so that sugar level in the blood comes back to normal.

Therefore, if there is not enough insulin produced by pancreas, blood sugars will rise which can be fatal. That's why some diabetic patients take insulin shots to regulate their blood glucose levels.
