Solution

The correct option is A Stomata
Plants lose water through stomata, lenticels, water stomata or hydathodes. Plants lose water in gaseous form or vapour form through stomata in the process of transpiration. The maximum amount of water is lost by the stomatal transpiration i.e., 50-90% water of total transpiration. Some amount of water may be lost through lenticels as vapours. Water is lost in liquid form through hydathodes.
