Question

B)ray-finned fishes
C)lampreys
D)hagfishes
E)tetrapods

Accepted Answer

The lobe-fin clade includes tetrapods (such as amphibians, reptiles, birds, and mammals) as well as coelacanths and lungfishes, which have lobed fins that contain bones that are similar in structure to those found in the limbs of tetrapods. Chondrichthyans (cartilaginous fishes such as sharks and rays), ray-finned fishes, lampreys, and hagfishes do not belong to the lobe-fin clade.
