You are part of the research group that hypothesized that relative humidity played a role in the transpiration differences. What additional evidence might you provide to support your hypothesis?

A) Population A has a high water potential and loss due to transpiration because of the increased humidity.

B) Population B has less water loss due to transpiration due to less crowding, less shading and an increase in humidity.

C) Population B shows an increased loss of water through transpiration because the environmental conditions are windier and less humid.

D) Population A has a low water potential and loss due to transpiration because more crowded conditions result in lower humidity and less shading.
