Scolopendra (Centipede) is indeed a member of the phylum Arthropoda.

Arthropoda is the largest phylum in the animal kingdom and includes insects, spiders, crustaceans, and myriapods (like centipedes and millipedes). Centipedes belong to the class Chilopoda within Arthropoda.

Let’s analyze the other options: A) Euplectella and Spongilla are both types of sponges and belong to the phylum Porifera, so they are in the same phylum. B) Sea anemones belong to the phylum Cnidaria (or Coelenterata), not Echinodermata. C) Holothuria (Sea cucumber) belongs to the phylum Echinodermata, not Mollusca.
