Verified by Experts

The correct Answer is:
B
Leaf bladders occur in the aquatic carnivorous plants of Utrucularia (Bladderwort). Some of the leaf segments are modified to form small bladders. A bladder has sensitive hair, brached trigger bristles, a trap valve, internal and external glands for trapping and digesting small animals (e.g., water fleas).
