Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. Obelia.

  • Obelia is a genus of small, colonial marine hydroids belonging to the class Hydrozoa within the phylum Cnidaria.
  • Obelia is well-known for exhibiting metagenesis, also known as alternation of generations, which is a type of life cycle that alternates between asexual and sexual reproduction.
  • Metagenesis refers to the alternation between two distinct generations.
  • The asexual polyp stage and the sexual medusa stage.
  • This alternation allows Obelia to exploit different ecological niches and enhance its chances of survival and reproduction.
