Incorrect Classification

Correct Answer: E. Nematode – Invertebrate – Radial

For the animal kingdom, the simplest invertebrates are the sponges, which have no body symmetry. As animals become more advanced, invertebrates move from having no symmetry to having radial symmetry. The most advanced invertebrates have bilateral symmetry. Nematoda are round worms and are more advanced than the cnidarian like the jellyfish; therefore nematodes should have bilateral symmetry, not radial symmetry. Likewise, the chordate or vertebrate are all characterized as having bilateral symmetry. The only incorrect grouping is [E].
