Which of the following is covered by the Americans with Disabilities Act?

The Americans with Disabilities Act (ADA) is a civil rights law that prohibits discrimination based on disability across various aspects of public life. Among the options provided, public transportation services are specifically covered under the ADA, as they must ensure accessibility for individuals with disabilities. This includes providing accessible vehicles and services, so that people with disabilities can travel freely and equitably.

Private sports clubs, personal training services, and private instructional centers typically do not fall under the same level of regulation as public services do. The ADA's intent is to ensure that people with disabilities have equal access to public spaces and services, which is why public transportation is a clear example of what the law encompasses.
