Answer: Negative
Explanation: A negative feedback loop has the major property of regulating on its own. It also becomes stable at certain point of time which makes it balancing feedback.The increment in the output of this system prevents the future generation of the feedback system.
The output gained as feedback is meant as the input in opposite direction in this system.Other options are incorrect because inverted feedback loop works in the inverted manner, positive feedback loop behaves as unstable system and convoluted feedback loop is not a technical term.
