Which statement best describes Type 2 diabetes according to the material?

• A. Type 2 is childhood onset with insulin insufficiency
• B. Type 2 is autoimmune destruction of beta cells
• C. Type 2 is adult onset with insulin insensitivity
• D. Type 2 is not related to insulin

Answer: (C)

Type 2 diabetes is defined by insulin resistance—tissues don’t respond well to insulin—so blood glucose stays high even when insulin is present. It most often appears in adults, frequently linked to overweight or obesity, and can involve a progressive decline in insulin production by the beta cells over time. This makes the statement about adult onset with insulin insensitivity the best fit. The other descriptions mix up the underlying patterns: autoimmune destruction of beta cells is what happens in Type 1, not Type 2; Type 2 isn’t defined by insulin insufficiency alone (though insulin production can wane later); and saying it isn’t related to insulin ignores the central role of insulin signaling in this type.
