Which system is responsible for the body's 'Fight or Flight' response?

The fight-or-flight response is driven by the sympathetic nervous system. When activated, it triggers the release of adrenaline-like catecholamines that speed up the heart, increase blood pressure, open airways, dilate pupils, and mobilize energy stores for quick action. The parasympathetic system does the opposite, promoting rest and digestion, so it isn’t responsible for this rapid, preparatory reaction. The other choices aren’t systems that regulate this response (one is a breathing difficulty state, the other a lack of oxygen), so they don’t describe the mechanism behind fight-or-flight.
