What are lobe-finned fish?
Lobe-finned fish, unlike other fish, have a core protuberance in their fins that contains many bones and muscles.
The fins are extremely flexible and may be useful for supporting the body on land, as seen in lungfish and tetrapods.
The majority of bony fish have ray fins. These thin fins are made up of skin webs that cover flexible spines. Lobe-finned fish, on the other hand, have fins that look like stumps.
The lobe-finned fishes are the ray-finned fishes' sister group. They are distinguished by paired, fleshy pectoral and pelvic fins espoused by a single bone.
Prehistoric records clearly show that terrestrial vertebrates evolved nearly 400 million years ago from lobe-finned fishes.
Thus, the correct option is A.
