Which of the following would NOT be a sign of developmental disability?

The ability to understand complex directions would not be a sign of developmental disability because developmental disabilities often affect cognitive functions, including learning and understanding. Individuals with developmental disabilities may struggle with tasks that require comprehension or processing of complex information, leading to challenges in communicating and following rules. In contrast, the ability to understand complex directions indicates a higher level of cognitive function, which is generally not characteristic of developmental disabilities.

The other options, such as difficulty in communication, following rules, and being self-sufficient without support, are more aligned with the characteristics typically observed in individuals with developmental disabilities. These difficulties stem from challenges in cognitive, social, and practical skills, which are central to developmental disabilities.
