An animal that encounters food and threats from several directions has body parts arranged around a central axis. Which body-plan feature best describes this arrangement?

  1. A

    Bilateral symmetry, because one plane divides the body into left and right halves.

  2. B

    Asymmetry, because no regular plane divides the body into similar halves.

  3. C

    Radial symmetry, because body parts are arranged around a central axis.

  4. D

    Segmentation, because the body is divided into repeated units.
