Step-by-step explanation:
The question asks whether tennis shoes are acceptable to wear in an operating room. The correct answer is D. No, Mark would need to change his shoes to non-cloth material and wear shoe covers. In an operating room setting, personnel are typically required to wear special footwear that is easy to clean and does not harbor bacteria or other contaminants. Cloth materials can trap contaminants and are not ideal for such sterile environments. Therefore, even if tennis shoes are worn, they must be non-cloth, and additional protective shoe covers must be used to maintain the sterility of the environment.
