Based on the context you've provided, if you have a map that indicates the deposits in Europe, I would recommend looking at which resource is depicted as more abundant. In general, Europe is known to have significant coal reserves, particularly in countries like Germany, Poland, and Ukraine. Iron ore deposits are also present but in lesser quantities compared to coal in many areas.
If you are specifically asking for the resource that Europe has the most deposits of, based on broad geographical knowledge, the answer would typically be Coal. However, for a definitive answer, it would be best to refer to the specific map to confirm.
