In deuterostomes, the anus forms from the blastopore. Which phyla are deuterostomes as listed?

Explanation:
In deuterostome development, the anus forms from the blastopore, and the mouth forms later. This pattern is seen in echinoderms and chordates, which share this developmental mode. The other groups listed are protostomes (mouth forms first from the blastopore, with the anus forming later) or non-bilaterians, so they don’t fit this pattern. Therefore, the phyla that are deuterostomes are echinodermata and chordata.
