The kingdom Plantae includes cryptogams and phanerogams. Cryptogams are plants in which the reproductive organs are inconspicuous. Thallophytes, bryophytes, and pteridophytes are cryptogams as their reproductive organs are not clearly visible or distinct. On the other hand, phanerogams include seed-producing angiosperms and gymnosperms, which have distinct and well-differentiated reproductive organs. Poriferans and cnidarians belong to the kingdom Animalia. Protists belong to the kingdom Protista.
Thus, option A is correct.
