Explanation:
Soil structure refers to the arrangement of soil particles into small clumps, called aggregates. These aggregates are held together by organic matter, clay, and other cementing agents, and they determine the soil's permeability, water-holding capacity, and resistance to erosion.
The sensitivity of a soil is a measure of how much it will shrink and swell as it dries and wets, respectively. A soil with a sensitivity of 9 is highly expansive and prone to cracking and heaving. It will have a flocculent structure, which means that its aggregates are loosely arranged and easily disrupted. This is because the high clay content in the soil causes the particles to repel each other, rather than stick together.
On the other hand, a soil with a honeycomb structure has a low sensitivity and is well-aggregated, with stable pore spaces that allow for good drainage and aeration. A soil with a dispersed structure, meanwhile, has a high sensitivity and is poorly-aggregated, with unstable pore spaces that lead to poor drainage and compaction.
Therefore, the correct answer is option C, flocculent structure.
