What increases the range of an electric vehicle?

You chose correctly. The range of an electric vehicle can be increased by using a high recuperation level, as this allows energy to be recovered during braking or coasting, returning it to the battery. Reducing the heater temperature also helps, since heating uses a significant amount of energy in electric vehicles. By lowering the heater, less energy is drawn from the battery, extending range. Short, sharp acceleration, however, uses more energy and reduces range, which is why it is not a correct answer. For best efficiency and range, drive smoothly, use high recuperation when appropriate, and minimize use of energy-intensive features like heating.
