The correct order of soil horizons, from the surface down to the unweathered bedrock, is O (organic layer), A (topsoil), E (eluviated or leached zone), B (subsoil), C (weathered parent material), and bedrock. Option A correctly follows this order. Option B incorrectly places horizon D in between horizons C and E. Option C places horizon E above horizon A, which is incorrect. Option D lists horizons in reverse order, starting with the deepest horizon, which is bedrock.
