Correct Answer: A
Solution :
Heterophylly is met with in many aquatic plants, particularly in those growing in shallow running water. Here the floating or aerial leaves and the submerged leaves are of different kinds; the former are generally broad, more or less fully expanded and undivided or merely lobed; while the latter are narrow, ribbon-shaped, linear or much dissected. Examples are Sagittaria, Ranunculus aquatilis, Limnophila heterophylla.
