Type 1 diabetes is defined by which characteristic?

Explanation:
Type 1 diabetes occurs when the pancreas stops producing insulin due to autoimmune destruction of the insulin-producing beta cells. Without insulin, glucose cannot enter most body cells, causing high blood sugar and the need for insulin therapy. This is why the description that fits Type 1 is that the pancreas no longer produces insulin. The idea of insulin overproduction would lead to low blood sugar, not diabetes. Insulin receptor damage would cause insulin resistance (more typical of Type 2), and having blood sugar stay permanently low would be hypoglycemia, not diabetes.
