- **Option A:** This option might include commonly used materials or tools in PEG placement, such as guidewires or dilators, making it an incorrect choice as these are indeed used.
- **Option B:** Similarly, this could represent another tool or material integral to the PEG procedure, such as the endoscope itself, which is essential for guiding the tube into place.
- **Option C:** This might represent a type of material or tool occasionally referenced in the context of PEG tubes or their placement, making it incorrect if it's indeed utilized.

## **Clinical Pearl / High-Yield Fact**
