Which law banned discrimination on the basis of disabilities in all federally funded programs in the US?

Section 504 of the Rehabilitation Act is a groundbreaking piece of legislation that specifically prohibits discrimination based on disability in programs and activities that receive federal funding. Enacted in 1973, it was one of the first laws to ensure that individuals with disabilities have equal access to services, education, and employment opportunities that are available to individuals without disabilities. This clause plays a crucial role in promoting inclusivity by mandating that any organization or program receiving federal assistance must provide equal opportunities to disabled individuals, thereby laying the groundwork for later laws, such as the Americans with Disabilities Act.

The other options, while significant in their own right, do not directly address the broader issue of discrimination in federally funded programs. The Architectural Barriers Act focuses primarily on accessibility standards for federal buildings, the Americans with Disabilities Act expands on protections but was enacted later, and the Air Carrier Access Act is specific to air travel rather than a wide range of federally funded programs.
