The process that is non-functioning in the person with diabetes is negative feedback mechanism. The correct option is B.
<h3>What is negative feedback mechanism?</h3>
A self-regulating system is a negative feedback loop, also known as an inhibitory loop. Increased output from the system inhibits future production in a negative feedback loop.
When blood glucose levels are too low, the pancreas secretes the hormone glucagon. This travels to the liver in the blood and causes glycogen to be broken down into glucose.
When glucose enters the bloodstream, glucose levels return to normal. This is an illustration of negative feedback.
Thus, the correct option is B.
