Vedclass · Answer

(A) The phylum $Chordata$ is characterized by the presence of a notochord, a dorsal hollow nerve cord, and paired pharyngeal gill slits.Vertebrates are a subphylum of $Chordata$ that possess a vertebral column.Since all vertebrates have a notochord during their embryonic development, they are classified as chordates.However, not all chordates are vertebrates (e.g., Urochordates and Cephalochordates do not have a vertebral column).Therefore, the statement "All vertebrates are chordates" is true, while the reverse is false.
