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 used to investigate the subsurface conditions of a site before construction. Auger borings are not common in soils that require lateral support because the auger can easily collapse in these soils.
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:
