Which of the following is NOT a purge type?

Explanation:
Purging the breathing loop in closed‑circuit diving is about clearing water and non‑breathable gas so you breathe clean, properly mixed gas and avoid gas-pocket issues. Preliminary purge is done on the surface to push out water and contaminants before entry. Surface purge is performed to ensure the loop has a clean gas path as you transition to diving. Emergency descent purge describes purging during an emergency descent to maintain safe breathing gas as you descend. Stability purge isn’t a recognized purge method in standard training, so it isn’t a purge type.
