Select the most appropriate option to fill in blank number 1.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. living.
The word "living" is appropriate because it describes something that is currently alive or existing. In this context, the tuatara is being distinguished as the only surviving member of its ancient reptile group.
Words like "being", "entity", or "life" do not fit grammatically or contextually because they do not convey the idea of "still alive" as clearly as "living" does.
