Final answer:

The R horizon in the soil profile contains unweathered bedrock and fragments.


Explanation:

Soil Horizon Containing Partially Weathered or Unweathered Rock

The soil horizon that contains a layer of partially weathered or unweathered rock is the R horizon. This layer consists of unweathered, parent bedrock and fragments.

Below this R horizon lies the C horizon, which is a layer of mechanically weathered bedrock or regoliths.

Additionally, the B horizon, located below the A and E horizons, is characterized by the accumulation of clay, iron, and other elements from the overlying soil.
