Which of the following is true of developmental disabilities?

Developmental disabilities encompass a range of conditions that affect physical, learning, language, or behavioral abilities. The statement that they restrict physical and mental ability accurately reflects the broad nature of these disabilities, which can impact various aspects of a person's functioning and development. Individuals with developmental disabilities often face challenges in areas such as communication, self-care, and social skills, which may hinder their ability to function fully in everyday life.

The other options presented do not provide an accurate representation of developmental disabilities. For instance, stating that they only affect physical abilities ignores the cognitive and behavioral challenges that can be present. Suggesting that these disabilities only manifest in childhood overlooks the fact that some may not be identified until later in life, and many individuals continue to experience the effects into adulthood. Lastly, the assertion that developmental disabilities can be cured misrepresents the nature of these conditions, as they are generally viewed as lifelong and managed rather than cured.
