A phylum is a principal taxonomic category that ranks above class and below kingdom.
Answer is (A) Chordates.


Vertebrates are a group of animals that possess a single rod like structure (called Notochord and/or vertebral column) throughout their length.

Now, this possession is a characteristic feature of Phylum Chordata. Hence, the answer is CHORDATES .

In fact, the rest of the options, that is, Fishes, Amphibians and Reptiles all belong to the phylum Chordata as they possess this rod like structure at least once in their life (starting right from the embryo to the adult).
