Solution
Dispersal in cnidarians is achieved during the Larvae and Medusa phases of the life cycle.
In the life cycle of cnidarians, the medusa is the sexual phase. Medusae, being free-swimming, can disperse over a wide area. They produce eggs and sperm, and after fertilization, a larva is produced. This larva, known as a planula, is also free-swimming and can disperse even further. The planula eventually settles and develops into a polyp, beginning the cycle again.
So, the correct answer is "Larvae and medusa".
