Answer
D. Worms
Explanation
Protostomes are a group of animals that undergo a specific developmental mode known as protostomy, where the mouth develops before the anus during embryonic development. This group includes invertebrates such as annelids (worms), arthropods, and mollusks. Among the options given, worms are the only protostomes. Horses and humans are deuterostomes, and flowering plants do not fall into the animal classification of protostomes or deuterostomes.
