The correct answer is D. When discussing the heating capacity and efficiency of a heating system, a salesperson should explain that capacity pertains to the amount of heat generated by the system, while efficiency is about producing heat in a cost-effective manner. This distinction is crucial for clients to understand because it relates to both the system's capability to provide heat and how efficiently it does so in terms of cost and energy usage.

Option A is incorrect because capacity is not typically measured in percentage terms, but rather in units like BTUs (British Thermal Units), which leads us to the correct answer, B.

Option C is incorrect as the heating capacity required for homes can vary significantly based on factors like size, insulation, and climate conditions. It is not accurate to claim that homes of different sizes often have similar heating capacity needs.

Option E is incorrect because efficiency plays a significant role in determining the overall cost-effectiveness of a heating system. It is not trivial; in fact, it is a crucial aspect to consider when evaluating heating systems.

Option F is also incorrect as the heating system's capacity is indeed related to the size of the home. Larger homes will typically require a heating system with a higher capacity to adequately heat the space.
