A student is revising Animal Diversity-I: a chiton clings to rocks and has a shell divided into eight overlapping plates. What should the student write in the answer sheet?

Chitons belong to Polyplacophora and are recognized by eight dorsal shell plates. Their broad foot helps them attach firmly to rocky surfaces. This MCQ belongs to the Polyplacophora topic in Animal Diversity-I and is written to test concept understanding rather than memorized wording.
