Which of the following statements best describes the application of ADA requirements in M's business case?

The correct choice accurately reflects the Americans with Disabilities Act (ADA) requirements, which mandate that businesses ensure accessibility for individuals with disabilities. Under the ADA, equal access must be provided regardless of the number of employees a business has. This means that if a business is not compliant, it can be viewed as violating the rights of handicapped individuals by denying them equal access to goods and services. The intent of the ADA is to create an inclusive environment, which underscores the importance of accessibility in all places of public accommodation, irrespective of the size or employee count of the business.

The other options present misconceptions about the ADA's applicability; for example, the number of employees does not determine whether ADA standards must be met, making both limits on employee count and cost arguments irrelevant to compliance obligations. Therefore, the best description of the application of ADA requirements in M's business case is that they are violated due to inadequate access for individuals with disabilities.
