Verified step by step guidance

Understand the concept of homeostasis: Homeostasis is the body's ability to maintain a stable internal environment despite changes in external conditions.

Identify the role of negative feedback: Negative feedback mechanisms are processes that counteract changes in the body to maintain homeostasis.

Analyze the options: Consider how each statement aligns with the concept of negative feedback and homeostasis.

Focus on the correct description: Negative feedback systems work by initiating a response that opposes or reduces the effect of the initial stimulus.

Conclude with the correct understanding: The statement 'It reduces the effect of a stimulus to maintain homeostasis' best describes how a negative feedback system works.
