Answer Details
The brooders in fishes return to their parent's mouth for protection. Some fish species, such as cichlids, have a behavior called mouthbrooding, in which the female fish carries the eggs in her mouth until they hatch and the young fish continue to stay in the parent's mouth for protection until they are able to swim independently. During this period, the parent fish provide protection against predators and ensure that the young fish have enough food and oxygen to survive. Therefore, the correct answer is protection.
