To accurately determine which major trend in Europe is supported by the information in the map, it's important to consider the specific content of the map itself (which I cannot see). However, I can suggest how to evaluate each option based on common historical context:
A. The spread of the Black Death primarily affected Europe and parts of Asia, but the map likely would not focus on this spread outside these regions, making this option less likely to be supported.
B. The economic growth of European towns could be indicated by symbols or markings showing town populations or trade routes. If the map features major towns or centers of trade, this would support this option.
C. The development of major Christian centers would be supported if the map shows significant religious landmarks, churches, or pilgrimage routes throughout Europe and North Africa.
D. The importance of farming could be reflected in representations of agricultural areas, such as fertile regions or population distributions that hint at the significance of agriculture to those areas.
Without seeing the specific map in question, I would recommend focusing on identifying symbols that indicate towns, trade routes, religious centers, or agricultural regions to determine which option is most strongly supported. If the map highlights towns or trade routes, option B is likely correct; if it shows religious sites, option C is likely correct; if it shows agricultural lands, option D is likely correct.
If you can provide more detail about what the map depicts, I could offer more tailored guidance!
