Solution

The correct option is C

Unfavorable for human settlements


The correct option is C:

Explanation of the correct option:

  1. The Amazon River Basin, the world's biggest river basin, is located in South America and encompasses a considerable chunk of Brazil.
  2. It is well-known for the large number of lethal organisms that seek refuge in its ecosystem.
  3. The Amazon River basin is extensively forested. The trees are dense, and there are few places suited for settlements.
  4. Furthermore, the forests are home to thousands of different bird, animal, and insect species, many of which are lethal predators or highly venomous.
  5. As a result, the area is unsuitable for human settlement.

Explanation of the incorrect option:

Option A:

  1. The Amazon is situated in a humid tropical climate. Because the atmosphere has a lot of moisture, it produces a lot of rain.
  2. It is also the world's largest river basin, having an enormous water supply. It is not a drought-prone location, but it does receive a lot of rain.

Option B:

  1. Swamps are areas that serve as a transition between water and land. They are wetland areas with marshy soil. Depending on its location, the soil may be flooded by saltwater or freshwater.
  2. There are marshes in some sections of the Amazon, although they are much smaller.

Option D:

  1. Tropical soils aren't recognised for being particularly fertile. The Amazon region also lacks a source for any sediments that might be carried into the forests by rivers.
  2. The nutrients and fertility of the soil on which the forests grow have depleted.

Final answer: Amazon basin is mainly unfavorable for human settlements.
