A student is revising Animal Diversity-I: an animal can be divided into similar halves by several planes passing through its central axis. What should the student write in the answer sheet?

This MCQ belongs to the Animal architecture topic in Animal Diversity-I and is written to test concept understanding rather than memorized wording.
