Which of the following country has the highest biodiversity?

Brazil

The correct answer is Option (1)- Brazil

Brazil is renowned for having the highest biodiversity in the world. This is primarily due to the vast and diverse ecosystems within its territory, including the Amazon rainforest, which is the largest tropical rainforest in the world and home to an extraordinary variety of plant and animal species. Brazil's biodiversity is unmatched, with a wide range of species, including many that are endemic (found nowhere else in the world).

Although India has only 2.4 per cent of the world’s land area, its share of the global species diversity is an impressive 8.1 per cent. That is what makes our country one of the 12 mega diversity countries of the world. Nearly 45,000 species of plants and twice as many of animals have been recorded from India.
