Type 1 diabetes:
a. is a condition in which no insulin is produced by the body.
b. typically occurs in patients between 50 and 70 years of age.
c. is defined as a blood sugar level that is less than 120 mg/dl.
d. is typically treated with medications such as metformin (glucophage).
the answer is A. simply because the first thing about diabetes(any kind) is that there is either a lack of insulin or it isn't being produced at all. in the case of type 1, its not being produced at all.
