The Auger borings are not common A. In soils that require lateral support B. In cohesive soils C. In soft soils D. None of the above

The correct answer is: A. In soils that require lateral support.

Auger borings are a type of soil boring that uses a rotating auger to remove soil. They are typically

Cohesive soils are soils that have a high clay content. They are relatively strong and do not require lateral support. Soft soils are soils that have a low clay content. They are relatively weak and require lateral support.

Here is a brief explanation of each option:

• Option A: In soils that require lateral support. Auger borings are not common in soils that require lateral support because the auger can easily collapse in these soils.
• Option B: In cohesive soils. Cohesive soils are soils that have a high clay content.

  They are relatively strong and do not require lateral support.
• Option C: In soft soils. Soft soils are soils that have a low clay content. They are relatively weak and require lateral support.
• Option D: None of the above. This option is not correct because auger borings are not common in soils that require lateral support.
