Choice C is false because negative feedback involves a response that opposes the change in the regulated variable, meaning that the input and output do not continue to enhance each other. Instead, the feedback loop works to counteract any deviation from the set point. A and D are true statements about negative feedback, and B is a valid description of negative feedback, although it is not the most commonly used definition.
