Hey Maja, for 2 a) could E be a good answer? It is a mineral horizon used in the united states, and I don't think any soil development occurs on that horizon given that mostly quartz is left behind. Or should we only consider A, B, and C as the mineral horizons.

E (as used in the US soil classification system) is the same as Ae (in Canadian system). But regardless of the system, E (or Ae) is the horizon characterized by the soil process of eluviation (or leaching out of either clay particles and/or organic matter) indicating that soil development is taking place. Hence, E (or Ae) cannot be the answer for question 2a. The answer is among A, B and C horizons........
