C Correct answer
Explanation

Colura zoophaga is a small epiphytic liverwort . It possesses elongated water sacs formed by the fusion of the upper leaf margin rolling inward down to the rest of the leaf. A funnel-shaped channel at the lower leaf margin leads to a small opening into the water sac and is covered by a movable lid that only open inward. It is because of this bladder-like configuration that these traps have been compared to those of Utricularia.
