Which of the following best explains the phenomenon of heterophylly observed in buttercup?
| 1. | The plant produces different leaf shapes at juvenile and mature stages due to internal genetic programming |
| 2. | The plant develops distinct leaf forms in water versus air, demonstrating environmentally induced plasticity |
| 3. | The plant undergoes mutation in response to changing seasons, altering its leaf morphology permanently |
| 4. | The plant mimics the leaf shape of neighboring species as an adaptive survival mechanism |
