The correct matching pair is (3) Ctenophora - Bioluminescence - Pleurobrachia.

Here's why:

1) Porifera - The characteristic feature of Phylum Porifera is the presence of pores or ostia, not cnidoblasts. The animal Hydra belongs to the Phylum Coelenterata (or Cnidaria), not Porifera.

2) Coelenterata - The characteristic feature of Phylum Coelenterata (or Cnidaria) is the presence of cnidocytes (stinging cells), not collar cells. The animal Sycon belongs to the Phylum Porifera, not Coelenterata.

3) Ctenophora - The characteristic feature of Phylum Ctenophora is bioluminescence (the ability to emit light). The animal Pleurobrachia also belongs to this phylum. So, this is the correct pair.

4) Platyhelminthes - The characteristic feature of Phylum Platyhelminthes is the presence of hooks and suckers. However, the animal Ascaris belongs to the Phylum Nematoda, not Platyhelminthes.
