Options
- AA-(iii), B-(iv), C-(i), D-(ii)
- BA-(iii), B-(i), C-(iv), D-(ii)
- CA-(ii), B-(iv), C-(i), D-(iii)
- DA-(iv), B-(iii), C-(i), D-(ii)
Correct answer
A. A-(iii), B-(iv), C-(i), D-(ii)
Step-by-step solution
Cyclostomata are jawless vertebrates that have an elongated body bearing 6-15 pairs of gill slits for respiration. Chondrichthyes are cartilaginous fishes with tough skin containing minute placoid scales. Osteichthyes are bony fishes that possess an air bladder which regulates buoyancy. In Cephalochordata, the notochord extends from the head to the tail region and is persistent throughout their life. Therefore, the correct matching is A-(iii), B-(iv), C-(i), D-(ii). Answer: A-(iii), B-(iv), C-(i), D-(ii)
