The recommended order for removing personal protective equipment (PPE) is crucial for maintaining safety and preventing contamination. The correct choice of removing shoe covers first is significant because they could track contamination from the environment onto the cleaner surfaces. Following the shoe covers, gloves are removed, as they often come into contact with contaminants. Next, goggles are taken off because they protect the eyes and should be removed before the mask to prevent any potential splash or droplet exposure to the face. Finally, the mask is removed last, as it serves to protect the wearer from inhaling contaminants and exposure from the environment.

This sequence is designed to minimize the risk of spreading contaminants from the areas that have been protected to areas that are clean. Each step in this process has a rationale rooted in infection control and safety protocols, hence making the chosen answer the most appropriate removal sequence.
