Step-by-step explanation:
The Amazon Basin predominantly falls within the elevation range of 100 to 500 meters above sea level, so the correct answer to the student's question is option A.
The basin is a large, low-lying area that supports the vast Amazon rainforest, which is known for its extensive biodiversity and is characterized by its flat and flood-prone terrain.
The presence of rainforests and jungle fauna, as well as the climate being tropical and humid with heavy precipitation, are indicative of the generally low elevation of the basin compared to higher landforms such as mountains and plateaus.
The correct option is A.
