Answer»

The CORRECT choice is (c) Notochord is formed from epidermal cells

To explain I WOULD say: Notochord is a rod-like structure formed on the dorsal side of animals. During the embryonic DEVELOPMENT, notochord GETS developed from mesodermal cells. Animals are classified as chordates and non-chordates based on the presence or absence of notochord. Pisces are an example for chordates.
