Solution
The correct option is B BAP
Transpiration is the loss of water in the form of water vapour from the parts of the plant. This takes with the help of stomata that are mostly present on the lower surface of leaves. The chemicals applied on leaves of plants to reduce the rate of transpiration are called antitranspirants. Antitranspirants are used to improve the crop yield in drought affected areas. Phenyl mercuric acetate (PMA) and low viscosity silicon oil are antitranspirants. Benzo[a]pyrene (BAP) is not an antitranspirant. Thus the correct answer is option B.
