Solution

The correct option is C Only iii is incorrect
Earthworms are reddish-brown invertebrates that live in upper layer of moist soil. Pheretima & Lumbricus are the most common Indian earthworms. Earthworms have long cylindrical body. The body of the earthworm is divided into about 100-120 segments. The dorsal surface of the body is distinguished by a dark median mid dorsal line (dorsal blood vessel). The ventral surface is marked by the presence of genital pores. Anterior end contains the mouth and the prostomium, a lobe which covers the mouth. Earthworms are invertebrates as they lack notochord.
