Which of the following defines a "disability" under the ADA?

The definition of a "disability" under the Americans with Disabilities Act (ADA) encompasses a broad range of physical or mental impairments that substantially limit one or more major life activities. To qualify as a disability, an individual must meet specific criteria, including having a physical or mental impairment that significantly restricts their ability to perform everyday tasks or activities. This comprehensive definition ensures that various conditions are recognized under the ADA, allowing for a wider array of individuals to receive necessary protections and accommodations in areas like employment, transportation, and public services.

The other options do not accurately reflect the ADA's definition of disability. For instance, focusing solely on mental impairments excludes many individuals with physical disabilities. Significant injuries alone do not constitute the legal definition, nor does the requirement for documentation through medical records capture the full scope of what may be considered a disability under the law. Thus, understanding that the ADA defines disability in relation to both physical and mental impairments, and specifying that these impairments must substantially limit major life activities, is crucial.
