The statement "Transpiration rate of plant B > that of plant A" is likely to be correct. Transpiration is the process by which water is lost from a plant through its leaves in the form of water vapour. Air movement can affect the rate of transpiration because it helps to remove the water vapour surrounding the plant, creating a drier environment that encourages further water loss. In moderately turbulent air (such as in the case of plant B), the air movement is higher compared to still air (as in the case of plant A). As a result, the rate of transpiration is expected to be higher in plant B due to increased air movement and faster evaporation of water from the leaves. Hence, the correct answer is option 1
