Answer:
B. Open Stomata
C. Transpiration 
Explanation:
Even though plants take up a lot of water from their roots, they lose about 95% of it to the atmosphere in the process known as Transpiration.
Transpiration is done for several reasons: it cools the plant down, it enables plants to access the nutrients in the water as the water moves along the plant and it enables gaseous exchange. 
The gaseous exchange happens because carbon dioxide comes in from the same holes on the leaf that the water leaves through to the atmosphere, the open stomata.
