From the given statement –

Analysis of Conclusions:
Conclusion I: "Fishes, amphibians, and tigers belong to the same family."
This conclusion does not logically follow from the statements. The statements only tell us where these animals live; they do not indicate that they belong to the same family. In fact, fishes, amphibians, and tigers belong to different biological classifications (families).
Conclusion II: "Both the amphibians and tigers can live on land."
This conclusion is valid. According to the third statement, amphibians can live on land, and the second statement states that tigers live on land. Therefore, both can indeed live on land.
Conclusion:
Only conclusion II follows.
The correct option is (a) Only conclusion II follows.
