**Core Concept**
Autoclaving is a widely used method for sterilizing heat-resistant medical equipment, including glass vessels and syringes. This process involves exposing the items to high pressure and temperature steam, which kills microorganisms and other pathogens.

**Why the Correct Answer is Right**
Autoclaving is effective for glass equipment because it uses saturated steam at 121°C (250°F) under pressure, ensuring that all surfaces are exposed to the sterilizing agent. This process is particularly useful for equipment that cannot be sterilized by dry heat, such as glass syringes, which may crack or shatter at high temperatures. Autoclaving is also a quick and efficient method, reducing the risk of contamination and exposure to microorganisms.

**Why Each Wrong Option is Incorrect**
**Option A:** Ethylene oxide sterilization is typically used for heat-sensitive materials, such as plastics and rubber, which may not be suitable for glass equipment.
**Option B:** Dry heat sterilization is often used for heat-resistant materials, but it requires longer exposure times and higher temperatures, which may damage glass equipment.
**Option C:** UV light sterilization is not effective for sterilizing glass equipment, as it may not penetrate all surfaces and can be inactivated by surface contaminants.

**Clinical Pearl / High-Yield Fact**
When sterilizing glass equipment, it is essential to ensure that all surfaces are exposed to the sterilizing agent, as microorganisms can survive in crevices and hidden areas.

**Correct Answer: A. Autoclaving**
