Answer 2

Classification of Porifera:

• Option “B” is correct i.e. Spicules.

• The classification of Porifera is based on spicules.

• The structure of spicules differs in every class of Porifera. It can be larger, smaller or have a different number of rays.

Symmetry, branching, and reproduction cannot be criteria for an arrangement of Porifera since they all are asymmetric, irregular branches and they make gemmules for reproduction.
