What does the US Federal Acquisition Regulation implement?

The correct choice pertains to Section 508 of the Rehabilitation Act. The US Federal Acquisition Regulation (FAR) implements government-wide rules for federal procurement, including the requirements set forth by Section 508. This section mandates that federal agencies ensure that their electronic and information technology is accessible to people with disabilities. The implementation of Section 508 within the FAR ensures that any products and services procured by the government meet accessibility standards, thus promoting equal access and opportunities for individuals with disabilities in accordance with the law.

The other options relate to different laws and regulations: the Affordable Care Act primarily addresses healthcare reform; the Americans with Disabilities Act aims to prevent discrimination in various sectors, including employment and public accommodations; and the Family and Medical Leave Act provides rights concerning job protection during family or medical leave. While all these laws are important in promoting rights and access, they are not directly implemented through the Federal Acquisition Regulation.
