Solution

The correct option is (a).

Explanation

The Amazon Basin is the largest river basin in the world, situated in South America. It defines the extent of the Amazon Rainforest and is geographically centered around the equator.

Statement 1 is Correct: The Amazon Basin is located in the tropical equatorial region. This region is geographically defined as extending between 10°N and 10°S latitudes. This latitudinal extent results in a hot and wet climate throughout the year, supporting dense tropical evergreen forests.

Statement 2 is Incorrect: The Amazon River originates in the Andes Mountains in the west (specifically in Peru) and flows eastward across the continent to reach the Atlantic Ocean in the east. The statement incorrectly suggests the river flows from east to west.

Statement 3 is Incorrect: The Amazon Basin drains portions of Brazil, Peru, Bolivia, Ecuador, Colombia, and Venezuela. It does not drain Chile. Chile is separated from the Amazon Basin by the Andes Mountains, which act as a major watershed; rivers in Chile generally flow westward into the Pacific Ocean.

Key Takeaway: The Amazon River flows from West (Andes) to East (Atlantic). Its drainage basin covers a vast portion of South America but excludes countries west of the Andes, such as Chile.
