According to the ADA, which of the following qualifies someone as disabled?

The Americans with Disabilities Act (ADA) defines disability in a broad manner, encompassing not only those with visible physical impairments but also individuals who may have a history of impairments or conditions that significantly impact major life activities.

Option C is correct because it recognizes individuals who have a record of impairment affecting major life activities, which is an essential aspect of the ADA's comprehensive approach to defining disability. This means that even if a person's impairment does not currently limit their activities, having a documented history of such an impairment qualifies them under the ADA. This understanding is crucial as it embodies the intention of the ADA to protect individuals against discrimination based on both current and past conditions that may affect their capabilities.

In contrast, the other options are limited in scope and do not adhere to the inclusive definitions set forth by the ADA. Those options either restrict the definition to only visible impairments or exclude individuals who have formerly faced significant limitations, which does not accurately reflect the legislative intent of the ADA concerning discrimination and accommodation for all individuals with disabilities.
