The correct answer is C. Dodo.
The dodo was a flightless bird that lived on the island of Mauritius in the Indian Ocean. It was about the size of a turkey and had a large, heavy body, short legs, and a long, thick neck. The dodo was a herbivore and its diet consisted mainly of fruits, nuts, and seeds.
The dodo became extinct in the late 17th century, probably due to a combination of factors, including hunting by humans, the introduction of predators such as dogs and cats, and the destruction of its habitat.
The dodo is often used as an example of a species that has been driven to extinction by human activity. It is also a symbol of the fragility of the natural world and the importance of conservation.
