The Rehabilitation Act of 1973 prohibits discrimination based on which factor?

The Rehabilitation Act of 1973 is a significant piece of legislation aimed at protecting individuals with disabilities from discrimination in various areas, particularly in federally funded programs and activities. The key focus of this act is to ensure that individuals with disabilities have equal access to opportunities and resources, which includes employment, education, and other public services. The act sets the framework for accessibility and non-discrimination, establishing that individuals with disabilities should not face barriers due to their physical or mental impairments.

Therefore, the correct answer highlights that the act specifically prohibits discrimination based on disability, making it illegal for entities to treat individuals unfairly because of their disabilities. This federal law plays a crucial role in advocating for the rights and inclusion of those with disabilities within society.

While other factors such as race, education, and income can be relevant in different legal contexts, the Rehabilitation Act's primary focus is on disability discrimination. This emphasizes the importance of recognizing barriers faced by individuals with disabilities and ensuring they receive equitable treatment and opportunities.
