The correct answer is option 1: Extinct. The Dodo bird is famously known for being extinct. Extinct means that a species no longer exists in the world. The Dodo bird was native to the island of Mauritius in the Indian Ocean and became extinct in the mid-17th century. It is believed that human activity, including hunting and the introduction of new species to the island, contributed to the extinction of the Dodo bird. There are no known living individuals of this bird species today. Extinction is a serious concern because once a species is gone, it cannot be brought back. Efforts are made worldwide to protect endangered and critically endangered species to prevent them from becoming extinct.
