  • A
    They are considered living fossils.
  • B

  • C
    Coelocanth, a lobelin fish, was caught in South Africa in 1938.
  • Correct answer
    D
    They had stout and strong fins, so they could go to land and come back to water.

Solution

According to evolutionary history, lobefins (such as the Coelacanth) were the ancestors of the first amphibians. A striking feature of these fishes was that they possessed stout and strong fins. This anatomical adaptation allowed them to move out of water onto land and then return to water, which was a crucial step in the evolution of terrestrial vertebrates.

Answer: They had stout and strong fins, so they could go to land and come back to water.

Hence, the correct answer is option: 'D'.
