Solution:
Fragmentation is a form of asexual reproduction that involves mechanical breaking a parent body into several pieces and each piece growing into a new individual. Multi-cell mold, algae and protonema of mosses shows fragments. All of them do not have a diplontic life cycle. All of them do not belong to the same kingdom. Mode of nutrition is different too.
They have a multicellular fibre-like vegetative called hyphae/ filaments/ protonema under certain natural conditions that can receive fragments or similar pieces, each with the potential to develop into new hyphae of a plant. Therefore, the correct answer is 'Multiplication by division'.
