The correct answer is A) executive function.

To determine this, let's go through the options and understand their meanings.

A) Executive function refers to a set of cognitive processes that involves planning, organizing, and carrying out tasks. It encompasses activities such as decision-making, problem-solving, and self-control. In this case, Ed's difficulty in planning and organizing the behaviors needed to complete the task of getting dressed indicates impairment in executive function.

B) Agnosia is a condition characterized by an inability to recognize or identify familiar objects or people, despite intact sensory abilities. This does not align with Ed's difficulty in getting dressed.

C) Apraxia is a motor disorder characterized by the inability to perform purposeful movements or coordinate movements, despite having the physical ability to do so. This does not fully explain Ed's difficulty in planning and organizing the task.

D) Aphasia refers to a language disorder that affects a person's ability to express themselves or understand language, typically as a result of brain damage. While aphasia can impact a person's ability to communicate, it does not directly explain Ed's difficulty in getting dressed.

Based on the explanations above, we can conclude that Ed's difficulty is primarily related to his impairment in executive function.
