The choice is D: Cycling on city roads.
B. A person has an autoimmune illness that destroys the beta cells in the pancreas.
C. An individual's insulin receptors are not functioning correctly.
Diabetes mellitus is prevalent and relates to the regulation of blood sugar levels. It occurs when the pancreas fails to generate sufficient insulin or when the insulin receptors become resistant, which is crucial for balancing sugar levels in the bloodstream.
Type 1 diabetes results from total insulin production failure by pancreatic beta cells, which are damaged by the immune system.
In contrast, Type 2 diabetes arises from the body's cells developing resistance to insulin. Insulin continues to be produced but does not adequately manage rising glucose levels due to malfunctioning receptors on target cells.
Based on the explanations above, options B and C are indeed correct.
