- DPetiole
Explanation
The correct answer is B because the pitcher in a pitcher plant is a modification of the leaf blade. In these insectivorous plants, the leaf is specially adapted to trap insects to fulfill the plants nitrogen requirements. The leaf consists of three modified parts: the leaf blade forms the pitcher, the leaf tip forms the lid to cover the pitcher, and the petiole often becomes tendril-like to provide support. Therefore, the main body of the pitcher is structurally a modified leaf.
