Options
- A(A)-(I), (B)-(II), (C)-(IV), (D)-(III)
- B(A)-(II), (B)-(I), (C)-(IV), (D)-(III)
- C(A)-(II), (B)-(IV), (C)-(I), (D)-(III)
- D(A)-(III), (B)-(I), (C)-(IV), (D)-(II)
Correct answer
B. (A)-(II), (B)-(I), (C)-(IV), (D)-(III)
Step-by-step solution
In Urochordata, the notochord is present only in the larval tail (A-II). In Cephalochordata, the notochord extends from head to tail and is persistent throughout their life (B-I). In Vertebrata, the notochord is present during the embryonic period and is later replaced by a cartilaginous or bony vertebral column in the adult (C-IV). In Non-chordates, the notochord is completely absent (D-III). Therefore, the correct matching is (A)-(II), (B)-(I), (C)-(IV), (D)-(III). Answer: (A)-(II), (B)-(I), (C)-(IV), (D)-(III)
