  4. DHeterophylly in cotton, coriander and larkspur.

Correct answer

A. Heterophylly in larkspur

Step-by-step solution

Every plant follows different pathways as a response to the environment, to form different structures, the ability to do so is called plasticity. Heterophylly in some plants is an example of the same. These plants have leaves that have a different shape when they are juvenile and the shape changes when they mature. The given figure depicts the heterophylly seen in larkspur when its juvenile and when they turn into an adult plant.
