AI Explanation

The correct answer is D) A single zone system. The diagram GS-RA-09 illustrates a simple HVAC system with a single air handling unit serving a single zone or space. This is the defining characteristic of a single zone system, where a single thermostat controls the temperature and airflow for the entire conditioned area. The other answer choices, such as a dual duct system, terminal reheat system, or variable air volume system, involve more complex multi-zone HVAC configurations, which are not depicted in the provided illustration.
