Final answer:
Impaired intellectual functioning is best supported when a child diagnosed with Intellectual Disability (ID) is unable to put together a four piece jigsaw puzzle.
Step-by-step explanation:
The diagnoses of impaired intellectual functioning is best supported when a child diagnosed with Intellectual Disability (ID).
Impaired intellectual functioning can be evidenced by difficulties in daily activities such as dressing neatly or combing hair neatly. In addition, being unable to put together a four-piece jigsaw puzzle may indicate a cognitive disruption. These difficulties in daily activities and cognitive tasks are indicators of lowered intelligence associated with Intellectual Disability.
In this case, option C, where the child cannot put together a four piece jigsaw puzzle, aligns best with the diagnosis of impaired intellectual functioning.
