Explanation

To answer the question "What lies beneath the C-horizon?" we need to understand the structure of soil and its horizons.

### Step-by-Step Solution:

1. **Understanding Soil Horizons**: Soil is organized into layers known as horizons. The main horizons are A, B, and C. Each horizon has different characteristics and compositions.

2. **Identifying the C-Horizon**: The C-horizon is the layer of soil that is made up of weathered rock and mineral particles. It is located below the A and B horizons and is less affected by soil formation processes.

3. **What Lies Beneath the C-Horizon?**: Beneath the C-horizon, we typically find the bedrock or parent rock. This layer is composed of solid rock that has not yet been broken down into soil.

4. **Conclusion**: Therefore, the answer to the question is that beneath the C-horizon lies the bedrock or parent rock.

### Final Answer:
Beneath the C-horizon lies the bedrock or parent rock.
