The correct answer is leading strand.

Leading strand is the new dna strand which grows continuously in the 5' to 3' direction. DNA is made up of double helix of two complementary strands. In the times of replication the strands are separated.

DNA replication begins in the genome which is the origin of replication. DNA polymerase synthesizes new strands by process of adding nucleotides and do compliment each strand. It is performed in Vitro.

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.
