Which statement correctly matches a diabetes type to its description?

• A. Type 1: little or no insulin
• B. Type 1: insulin resistance with excess insulin
• C. Type 2: high blood glucose in pregnancy
• D. Gestational diabetes: autoimmune destruction of pancreas

Answer: (A)

The main idea is how insulin production and action define different diabetes types. Type 1 occurs when the immune system destroys the cells that make insulin, so there’s little or no insulin produced. Without insulin, glucose can’t enter body cells, causing high blood glucose, and people with Type 1 require insulin therapy to survive. This is different from Type 2, where the body becomes resistant to insulin or doesn’t make enough to overcome that resistance. Gestational diabetes describes high blood glucose that develops during pregnancy due to hormones that cause temporary insulin resistance, not autoimmune destruction. So the statement that Type 1 has little or no insulin correctly matches the actual mechanism, making it the best fit.
