Which one of the following is an insectivorous plant?

Result
Your answer: —  ·  Correct: B
Explanation

Pitcher plants are classic insectivorous (carnivorous) plants that employ a pitfall trapping mechanism: modified leaves form tubular or pitcher‑shaped traps into which insects slip and are digested, often aided by nectar, slippery rims and digestive fluids [1]. Genera such as Nepenthes and Sarracenia are well‑known pitcher plants found in tropical and temperate habitats; their pitchers capture and provide nutrients from arthropod prey, making them insectivorous by definition [2]. The other listed species—passion flower (Passiflora), night queen (Cestrum nocturnum) and flame of the forest (Butea monosperma)—are ordinary flowering plants and not carnivorous. Therefore option 2 (Pitcher plant) is the correct answer.
