Which of the following is classified as a developmental disability?

The classification of developmental disabilities primarily includes conditions that are attributable to physical or mental impairments that manifest during the developmental period, typically before the age of 22, and which can result in substantial functional limitations in major life activities. An intellectual disability specifically falls into this category, as it is characterized by significant limitations in both intellectual functioning and in adaptive behavior, which affects a person’s ability to carry out everyday activities. This aligns with the definition and criteria established for developmental disabilities, making it the correct choice.

In contrast, blindness, while it can result in significant challenges, is not classified as a developmental disability per se; rather, it is considered a sensory impairment. Neurological disorders are a broad category that can include developmental disabilities but are not limited to them, meaning not all neurological disorders are classified as such. Amputation, though it leads to physical limitations, is classified as a physical disability rather than a developmental one, as it does not typically arise from conditions affecting cognitive or adaptive functioning in the same way as intellectual disabilities do.
