"It counteracts changes by activating mechanisms to restore normal temperature."
Explanation: Negative feedback detects deviations from a set point (e.g., body temperature) and triggers responses that oppose the change (shivering and vasoconstriction when cold; sweating and vasodilation when hot) to bring the temperature back to normal. The other choices describe raising temperature indefinitely, keeping it below normal, or amplifying changes — those do not describe negative feedback.
