Correct answer: B. Pectoral and Pelvic.
- A. Dorsal and ventral.
- B. Pectoral and Pelvic.
- C. Tail and anal
- D. All of these
Explanation
Pectoral fins and pelvic fins are paired because they occur as corresponding structures on the left and right sides of the fish. The dorsal, ventral, tail and anal fins are generally median fins, so a student may incorrectly choose all of these.
