Answer:
The correct answer is 1: which was home to many other extinct species.
Explanation:
“Which was home to many other extinct species“ is a relative clause that provides us more information about something – in this case, about Tasmania.
The main function of relative clauses is to join two sentences and provide some additional information.
All relative clauses begin with some relative pronoun (which, when, who, where or that).
Because of that, we cannot consider other options as the correct answer.
The relative clause comes immediately after the subject or the object of the sentence. As mentioned, relative clauses refer to the noun that precedes, by giving us additional information about that noun.
