The question refers to soil classification in engineering, focusing on cohesive types. The correct answer is Type A, which includes clay and similar materials. These soils are characterized by their ability to stick together and provide structural support. ;
The correct classification that tends to be cohesive and includes materials like clay, cemented soils, and hardpan is Type A. Cohesive soils, characterized by their ability to stick together, provide crucial support in engineering contexts. This classification is key for understanding soil's behavior under structural loads.
