Demospongia is the class of sponges that includes the majority of sponge species, many of which are harvested commercially for use in products such as bath sponges and cleaning sponges. The other options, Hexactinellida, Sclerospongia, Spheciospongia, and Calcarea, are also classes of sponges, but they either have different uses (such as Hexactinellida, which are not commonly harvested due to their delicate structure) or are not typically used for commercial purposes.
