Final answer:
The Rehabilitation Act of 1973 stipulates that individuals with disabilities should not be discriminated against in any federal programs or activities, applies to a variety of public entities including transportation services, and requires equal access to electronic office equipment. Hence, the correct answer is 'd. All of the above.'
Step-by-step explanation:
The Rehabilitation Act of 1973 included provisions to ensure that individuals with disabilities were not discriminated against in federal employment or in programs run by federal agencies or receiving federal funding. It was a landmark step towards equal opportunity for all citizens, regardless of disability, and opened doorways to employment and accessibility in various public domains. The Act included requirements such as accessibility in public transportation and electronic office equipment, thus applying broadly to various public entities.
More specifically, the Act's Section 504 stipulated that no individuals with disabilities should be excluded from participation in, be denied the benefits of, or be subjected to discrimination under any program or activity receiving federal financial assistance. This included entities like transportation services. Furthermore, the Act established mechanisms for equal access to office equipment and technologies, a precursor to later digital accessibility standards.
