Ans. (A) 7

Just a few thousand years ago, tropical rainforests covered as much as 12 percent of the Earth's land surface, or about 6 million square miles (15.5 million square km), but today less than 7 percent of Earth's land is covered with these forests (about 2.41 million square miles or 600 million hectares). The largest unbroken stretch of rainforest is found in the Amazon river basin of South America. Over half of this forest lies in Brazil, which holds about one-third of the world's remaining tropical rainforests. Another 20 percent of the world's remaining rainforest exists in Indonesia and Congo Basin, while the balance of the world's rainforests are scattered around the globe in tropical regions.
