- D. Reducing the size of the heating area
Answer
Installing better thermal insulation
Explanation
The correct option is "Installing better thermal insulation". Installing better thermal insulation is right because it directly matches Efficiency: (HT only) Describe ways to increase the efficiency of an intended energy transfer.. The other options are less suitable because they change the required Physics relationship, confuse the relevant energy store or use a distractor that does not answer the question.
Common mistake
Misunderstanding Efficiency Improvements
Students often think that increasing the input energy will always increase the efficiency of a system.
Emphasize that efficiency is about maximizing useful energy output relative to total energy input, and that reducing wasted energy is key to improving efficiency.
