Solution

The correct option is B Echinoderms and Chordates
B. Echinoderms and chordates
Reason: We all know that Hemichordates are connecting link between chordates and non chordates. Hemichordates and echinoderms are generally considered as sister groups as they share similar relationship with each other. These two phyla are the nearest relatives of chordates; organisms that has a notochord. Their significant resemblance is their larval stage. Echinoderm larva is a bilateral in shape which is similar to the larval stage of hemichordates. They also have similarities in the arrangement of their coelomic cavities (tripartite coelom) and early embryogenesis. So option B is correct.
