Answer 1

The correct option is A Chordates

The notochord is the prime identifying structure of the chordates and the group derives its name from it. It is a rod-like elastic structure situated just above the alimentary canal and immediately beneath the dorsal tubular nerve cord. It helps in attachment of muscles and coordinates development. Notochord is present in a chordate at some stage of their life cycle.

So, the correct answer is option A.
