Arthropoda

Answer 2

The correct answer is OPTION 1: Arthropoda.

• The formation of segmented bodies, or Arthropoda, was the third mainline in invertebrate evolution, and it happened very recently, around the same period as jellyfish fossil patterns were discovered in Flinders, Australia.
• Mollusks and echinoderm larvae both feature twisted shapes and cilia bands that twist.
• Flatworms like Platyhelminthes are assumed to have descended from mollusks and arthropods, while echinoderms originated independently.
