Hemichordata

Target entity: Hemichordata
Context triple: [Deuterostomia, includes, Hemichordata]

• A. Cephalochordata
  Cephalochordata is a subphylum of small, fish-like marine animals (such as lancelets) that retain a notochord throughout life and are important for understanding vertebrate evolution.
• B. Urochordata
  Urochordata, also known as tunicates or sea squirts, is a subphylum of mostly sessile marine animals whose larvae possess chordate features such as a notochord and dorsal nerve cord.
• C. Echinodermata
  Echinodermata is a phylum of marine invertebrates that includes starfish, sea urchins, sand dollars, and sea cucumbers, characterized by radial symmetry and a water vascular system.
• D. Deuterostomia
  Deuterostomia is a major animal clade that includes chordates (such as vertebrates) and echinoderms, characterized by a distinctive embryonic development pattern in which the anus forms before the mouth.
• E. Lophotrochozoa
  Lophotrochozoa is a major clade of protostome animals that includes diverse groups such as annelid worms, mollusks, and brachiopods, united by shared developmental and molecular characteristics.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
