The correct answer is option 4, Chile. The Llanos are not actually located in Chile, but rather in Colombia and Venezuela, which are not listed as options in the question. The Llanos are vast grasslands that cover a large area of these two countries. They are characterized by wet and dry seasons, with heavy rains causing flooding during the wet season and dry conditions and fires during the dry season. The Llanos are known for their diverse wildlife, including birds, reptiles, and mammals, such as jaguars and capybaras. The grasslands are also used for agriculture and cattle farming. Therefore, it is important to note that the correct answer should be Colombia and Venezuela, instead of Chile.
