Solution
The correct option is C Earthworm
- Earthworm is not a deuterostome. Deuterostomes are distinguished by their embryonic development. In these animals, the first opening (the blastospore) becomes the anus, while in protostomes it becomes the mouth.
- Deuterostomes are also known as enterocoelomates because their coelom develops through enterocoely.
- There are four extant phyla of Deuterostomes-Chordata, Echinodermata, Hemichordata and Xenoturbella. Hence, option C is correct.
