HELP QUICKKK Which soil layer in the diagram above has the MOST nutrients available for plants growing in the soil?

I would think layer 2, or 3 because in layer 1 the plant has already used that nutrients and it doesn’t replenish fast enough and in layer four there are a lot of rocks that would make it possibly hard for the plant to grow further and the nutrients would prolly be used up possibly too.

Hope this helps
