Which of the following is a mode of asexual reproduction in corals?

Fragmentation is indeed a recognized mode of asexual reproduction in corals. In this process, a piece of the coral colony breaks off, either due to natural factors like water movement or physical disturbances, and can then settle in a suitable area, where it can grow into a new coral colony. This allows corals to propagate without the need for gametes, enabling rapid expansion of their populations, particularly in stable environments.

Understanding fragmentation is crucial because it demonstrates how corals can contribute to reef resilience and recovery, especially after disturbances such as storm damage. It also highlights the importance of maintaining healthy coral habitats where this type of reproduction can successfully occur. Other options involve sexual reproduction or larval stages, which do not fit into the asexual reproduction category.
