Final answer:
Health regulations require food preparation areas to be free of animals except for service dogs trained to assist individuals with disabilities. Option A is the correct answer.
Step-by-step explanation:
According to health regulations, every room where food is prepared, processed, packaged, served, transported, manufactured, handled, sold, offered for sale, or displayed must be kept free from live birds or animals with the exception of service animals. These regulations are in place to prevent contamination and spread of diseases. Service animals are defined as dogs that are individually trained to do work or perform tasks for the benefit of a person with a disability. This exception recognizes the vital role service animals play in assisting their handlers, while still upholding food safety standards.
