Question

what is the name of the phylum sponges belong to? 2/35

Explanation:

To determine the phylum sponges belong to, we recall biological classification: Sponges are in the phylum Porifera. Mammals are a class (not a phylum for sponges), chordates include vertebrates, and cnidarians are a different phylum (e.g., jellyfish). So the correct option is Porifera.

Answer:

D. Porifera (assuming the options are labeled with the green option as D; if labels are A: mammals, B: chordate, C: cnidarians, D: Porifera, then the answer is D. Porifera)
