Which statement about sterilization method parameters is incorrect?

Explanation:
Understanding sterilization parameters means recognizing that each method operates at its own temperature and time settings. Dry heat uses relatively high temperatures for a longer period, typically 300–375°F for about 60–120 minutes. Steam sterilization relies on saturated steam at about 250°F for around 20–30 minutes. Chemical vapor is typically around 270°F for about 20 minutes. Ethylene oxide is a low-temperature process, not hot like hundreds of degrees; it operates at roughly 122–140°F (50–60°C) with exposure for several hours and includes an aeration phase afterward. Therefore, stating EO at 320°F for 60–120 minutes is incorrect because EO does not use such a high temperature or this short exposure.
