Don’t mistake the option letter for the plant’s letter when answering questions like these. Temperature, because a higher temperature causes the plant’s leaves to release more water vapor, humidity, because a higher humidity level reduces the concentration gradient of water vapor between the air spaces of the leaves and the atmosphere, and wind speed, because a higher wind speed removes more of the water vapor that has accumulated around the leaves and stomata, increasing the concentration gradient between the air spaces of the leaves and the atmosphere.
