Consider the following pairs :

Country	Animal found in its natural habitat
1. Brazil	Indri
2. Indonesia	Elk
3. Madagascar	Bonobo

How many of the pairs given above are correctly matched?

The correct option is None.

Let us analyze each pair to understand why none of them are correctly matched:
1. Brazil and Indri: The Indri (Indri indri), also called the babakoto, is one of the largest living lemurs. It is endemic to the island of Madagascar, not Brazil.
2. Indonesia and Elk: The Elk (Cervus canadensis), also known as the wapiti, is one of the largest species within the deer family. Its natural habitat spans North America and Eastern Asia, not Indonesia.
3. Madagascar and Bonobo: The Bonobo (Pan paniscus), formerly called the pygmy chimpanzee, is an endangered great ape. Its natural habitat is strictly restricted to the humid forests of the Democratic Republic of the Congo in Central Africa, not Madagascar.

Since all three pairs are incorrectly matched, the correct count of correctly matched pairs is indeed zero (None).
