The correct option is B Bryophyllum and Kalanchoe
Some plants form detachable plantlets (small plants) in notches along their leaf margins. Kalanchoe, whose common name is mother of thousands, has meristematic tissue that gives rise to an individual plantlet at each notch in the leaf. When these plantlets reach a certain size, they drop to the ground, root and grow. Similarly, Bryophyllum also form plantlets from leaf margins.
