    The correct answer is option D, 520 Million Years Ago

    The first invertebrates occurred in the oceans in the form of soft body animals which are covered by shell. These organisms appeared in the water bodies some 5 billion years ago (500 million years ago). The other species include the arthopods (insects), mollusk (snails and octopus), annelids (Earthworm and leeches) etc. also evolved some 490 million years ago.
