B

Statement-I is incorrect but Statement-II is correct
C

Both Statement-I and II are incorrect
D

Both Statement-I and II are correct

Bony fishes (Chondrichthyes) have air bladder acting as a hydrostatic organ helping the fish float easily at the desired level without much expenditure of energy.
