Answer: The answer is bilateral.

Although echinoderms are radially symmetrical but still they more closely related to humans than to a jellyfish. Firstly, because of echinoderm larvae have bilateral symmetry which is similar to human( chordate) body plan. Secondly, because of Echinodermata and Chordata (human) both are deuterostomes(blastopore become anus), not protostomes(blastopore become mouth) like jellyfish
