Which statement is true about Type 1 diabetes?

• A. The pancreas no longer produces insulin
• B. It is caused by insulin receptor resistance
• C. It can be cured with diet alone
• D. It does not affect blood sugar control

Answer: (A)

In Type 1 diabetes, the immune system destroys the cells in the pancreas that make insulin, so little or no insulin is produced. Insulin is the key that lets glucose move from the blood into most body cells to be used for energy. Without insulin, blood glucose climbs high and cannot be properly controlled, which is why people with Type 1 need insulin therapy to survive.

The statement about insulin receptor resistance describes Type 2 diabetes, where the body's cells don’t respond well to insulin even if it’s present. Diet alone cannot cure Type 1, though careful eating helps manage blood sugar. And Type 1 does affect blood sugar control—without insulin, control is not possible.
