Correct Answer: Option (B) — Leaf

Concept & Option Breakdown

Standard Reference Verified

In pitcher plants (such as Nepenthes), the leaf blade (lamina) is modified into the hollow pitcher body, the leaf apex forms the lid (operculum), and the petiole often acts as a tendril to support the trap.

Elimination Heuristic & Exam Approach

In almost all carnivorous plant traps (Nepenthes, Dionaea, Utricularia), the insect-capturing mechanism represents a specialized morphological modification of the leaf.
