The Correct Answer is Option 'A' - Liquid

Soil is classified based on its water content and consistency. The percentage of water content in soil can determine its state, which can be liquid, semi-solid, plastic, or solid. In this case, if the water content is greater than 100%, the soil is considered to be in a liquid state.

Let's delve into the details of each state and understand why the correct answer is option 'A' - Liquid.

1. Liquid State:
- A soil in a liquid state means that it contains more water than necessary to fill the void spaces between the soil particles.
- The excessive water causes the soil to become saturated, resulting in a high liquidity index.
- In this state, the soil behaves like a liquid, allowing it to flow and settle easily.
- The particles in the soil are not bound together, and they freely move past each other due to the presence of excess water.

2. Semi-Solid State:
- A soil in a semi-solid state contains less water than a soil in a liquid state, but still more water than a soil in a plastic or solid state.
- The soil in a semi-solid state has a higher viscosity compared to a liquid state.
- It is not as free-flowing as a liquid, but it still retains some fluid-like characteristics.
- The particles in the soil are partially bound together, and they offer some resistance to deformation.

3. Plastic State:
- A soil in a plastic state contains even less water than a soil in a semi-solid state.
- In this state, the soil can be easily molded and retains its shape after deformation.
- The particles in the soil are partially bonded, allowing the soil to be molded without losing its form.
- However, the soil does not flow like a liquid or a semi-solid.

4. Solid State:
- A soil in a solid state contains the least amount of water among all the states.
- In this state, the soil is dry and does not exhibit any fluid-like characteristics.
- The particles in the soil are tightly packed and do not move past each other easily.
- The soil in a solid state is rigid and does not deform easily.

Conclusion:
Based on the given information that the water content in the soil is greater than 100%, the soil is in a liquid state. In this state, the excess water causes the soil to become saturated, resulting in a high liquidity index. The soil behaves like a liquid, allowing it to flow and settle easily.
