India is still a virgin land exploring its tourism potential.

undone
unexplored
uncouth
unexploited

The correct answer is unexplored.

  • Undone means not finished or completed. This does not make sense in the context of the sentence, as India is a country that has been explored by many people.
  • Uncouth means rude or ill-mannered. This does not make sense in the context of the sentence, as India is a country with a rich culture and history.
  • Unexploited means not used or taken advantage of. This is the closest answer to the correct answer, but it does not capture the full meaning of the sentence. India is a country with a lot of potential for tourism, but it has not been fully explored by tourists.

Therefore, the correct answer is unexplored.
