The correct option is B Environmental heterophylly in buttercup
Heterophylly is one of the methods of plasticity in which plants follow several pathways in response to the external environment or different phases of life to form different kinds of structures. The image shows difference in shapes of leaves produced in air
and those produced in water in buttercup. It represents the
environmental heterophylly.
Plants like cotton, coriander, and larkspur have leaves in juvenile phase which are entirely different from the mature phase. This is developmental heterophylly.
