**Core Concept**
Syringes and glassware are sterilized using a method that involves the use of high-pressure steam to inactivate microorganisms, resulting in a sterile product. This process is based on the principle of autoclaving, which involves the application of heat and pressure to eliminate microbial contamination.

**Why the Correct Answer is Right**
The correct answer is **Autoclaving**, which involves the use of a steam sterilizer to expose syringes and glassware to high-pressure steam at a temperature of 121°C for a specified period. This process is effective in inactivating bacterial spores, viruses, and other microorganisms, resulting in a sterile product. Autoclaving is a widely used method for sterilizing medical devices and equipment due to its effectiveness and ease of use.

**Why Each Wrong Option is Incorrect**
* **Option A:** **Dry Heat Sterilization** is a method that involves the use of hot air to sterilize equipment, but it is not as effective as autoclaving for heat-sensitive materials like syringes and glassware.
* **Option B:** **Ethylene Oxide Sterilization** is a method that involves the use of a toxic gas to sterilize equipment, but it is not commonly used for syringes and glassware due to its toxicity and the need for specialized equipment.
* **Option C:** **UV Light Sterilization** is a method that involves the use of ultraviolet light to inactivate microorganisms, but it is not effective for sterilizing syringes and glassware due to their material composition and the difficulty of achieving adequate penetration.

**Clinical Pearl / High-Yield Fact**
It is essential to note that autoclaving is not suitable for all types of medical devices, particularly those made of heat-sensitive materials like plastics and rubber. In such cases, alternative sterilization methods like dry heat sterilization or ethylene oxide sterilization may be necessary.

**Correct Answer:** A. Autoclaving.
