Which statement best describes the difference between Type I and Type II diabetes?

• A. Type I diabetes is insulin dependent; Type II diabetes is insulin resistance
• B. Type I diabetes is insulin resistance; Type II diabetes is insulin dependent
• C. Type I diabetes is autoimmune destruction of pancreatic beta cells
• D. Type II diabetes is autoimmune destruction of beta cells

Answer: (A)

The main idea is how insulin use differs between the two types: absolute insulin deficiency versus insulin resistance. Type I diabetes results from autoimmune destruction of pancreatic beta cells, leading to little or no insulin production, so patients are insulin dependent for survival. Type II diabetes is characterized mainly by insulin resistance—where the body's cells don't respond well to insulin—often with impaired insulin secretion, and many patients can manage early on without insulin (though some may need it later). The statement that best captures the difference is that Type I is insulin dependent while Type II is insulin resistance, which aligns with the typical clinical distinction. The other options either describe aspects of Type I or Type II inaccurately or focus on a mechanism (autoimmune destruction) that doesn’t contrast Type I and II.
