AIIMS 2018 Botany Leaf Modifications MCQ Question

Option C is correct because it identifies the third leaf that has undergone a modification to function as a root, a phenomenon known as a leaf modification or a leaf root. In certain plants, leaves can adapt to take on roles beyond photosynthesis, such as anchoring the plant or absorbing nutrients and water (H₂O) from the soil. The other options are not applicable as they do not correspond to the specific modification described in the question, which emphasizes the unique role of the third leaf in this context. Understanding these modifications highlights the versatility of plant structures in adapting to their environments.
