[2025-09-29T18:36:20.808718] [PI reasoning] **Analyzing sterilization methods**

I need to discuss the main disadvantage of dry heat sterilization, which is that it’s time-consuming. It requires longer temperatures (160°C for 60 minutes or 170°C for 30 minutes) compared to autoclaves (121°C for 15 minutes). So, I'll confirm that answer A is correct. While rusting isn’t an issue since moisture causes that, and dry heat is safe for sharp instruments, the primary drawback truly is the longer time needed. I should find sources to support this.
