Best answer
Correct option is (a) Hemichordates

Best explanation: Animals are classified considering several factors like level of organization in the organism, symmetry, arrangement of cells in the embryo, presence or absence of coelom, segmentation in the organism and presence or absence of notochord. Hemichordate is one such organism which has organ system level of organization, bilateral symmetry and body cavity.
