To answer your question, we need to consider the context of the political changes and divisions depicted on the map. Here are some insights into each option:
A. Business rivalries - While business rivalries can create tensions, they typically do not lead to significant political divisions on a larger scale.
B. Religious differences - Religious differences have historically played a major role in political divisions and conflicts, often intensifying existing divides.
C. Competition for oil-rich territories - Control over oil-rich territories can lead to intense political and military conflicts, especially in regions where resources are scarce and geopolitical interests are high.
D. Communist versus capitalist conflict - The Cold War period saw intense political divisions primarily defined by the ideological struggle between communism and capitalism.
Without the specific context of the map you are referring to, it is challenging to pinpoint the exact correct answer. However, if the map reflects geopolitical regions or historical conflicts influenced by ideology, options B, C, or D may be more fitting. If the map is about the Middle East, for instance, C could be especially relevant due to the competition for oil-rich territories.
