The production of four haploid gametes from one mother cell is completed during a) anaphase meiosis i. b) telophase meiosis i. c) prophase meiosis ii. d) telophase meiosis ii.

B) telophase meiosis

Explanation:

Meiosis is the process by which a cell is divided into a sexual cell that has half the pairs needed to create a new individual, when that cell is unified with another gamete with other half pairs needed a new individual is procreated, the phase of the meiosis where the production of the four haplois gamtes is completed is called telophase and its the last one of the process.

organisms that lack symmetry are called asymmetrical and belong to phylum porifera/sponges.

organisms with specialized stinging cells belong to phylum cnidaria. stinging cells are called cnidoblast cells.

cnidarians show two morphological forms : polyp (sessile) and medusa (mobile)

filter feeding is observed in porifera members.  

alternation of generation is observed in coelenterata or cnidaria. there is alternation of asexual polyp form and sexual medusoid form. it is also referred as metagenesis.
