An animal is radially symmetrical if:
Aonly one longitudinal plane can divide the body into equal halves
Bno plane through the centre can divide the body into equal halves
Cany plane through the centre of the body can divide it into equal halves
Dthe body can be divided equally only during embryonic development
Answer & Solution
Correct answer: C. any plane through the centre of the body can divide it into equal halves
In radial symmetry, any plane passing through the central axis can divide the body into similar halves. This is seen in cnidarians, ctenophores, and adult echinoderms.
