In the given flow chart,P could be parasitic plant,Q could be plant in desert habitat,R could be insectivorous plant and S could be plant situated near coastline.P does not possess hygroscopic roots. They are present in some orchids to absorb moisture from atmosphere.Leaves in desert plants are either absent or reduced or they are present in the form of spines.Stilt roots are adventitious roots that arise from the lower nodes and provide extra support to the plant.They are not meant for respiration. So,options A,B and D are incorrect.
