Setup 1 was the control of this experiment designed by Elle to test how temperature affects the rate of evaporation. Thus, the correct option is B.
Evaporation may be defined as a methodology where liquid transforms into a gas below the temperature at which it boils.
Setup 1 was the control because the room temperature (25°C) is an optimum temperature, where no chemical as well physical properties allow the substances to transform into another state.
Therefore, the correct option for this question is B.
