The correct option is C Echinodermata
Many of the earliest echinoderms either lacked symmetry or were bilaterally symmetrical. Bilateral symmetry occurs in all living groups and is especially marked in the larval stages. A tendency towards radial symmetry developed early in echinoderm evolution and eventually became superimposed upon the fundamental bilateral symmetry. Echinoderms exhibit secondary radial symmetry in portions of their body at some stage of life.
Therefore, the correct answer is option C.
