Solution
The correct option is B Vanda
Hygroscopic roots are present in Vanda. The stems of Vanda vary in size. The plants can become quite massive in habitat and in cultivation and epiphytic species possess very large, rambling aerial root systems. Hygroscopic roots may receive water and nutrient from the air. There are many types of aerial roots used for aeration and not for water absorption. In other cases, they are used mainly for structure and in order to reach the surface. These roots function like regular terrestrial roots. Most aerial roots directly absorb the moisture from fog or humid air.
Thus, the correct answer is option C.
