Which of the following is not an accepted form of instrument marking?

Barcoding
Etching
Ink stamping
Engraving

The correct answer is: Engraving

Engraving is not an accepted form of instrument marking in the sterilization process. Engraving can create grooves or ridges on the instrument's surface, which can harbor bacteria or make the instrument harder to clean thoroughly. Barcoding, etching, and ink stamping are accepted methods of instrument marking as they do not compromise the integrity of the instrument or create areas where debris can collect.
