Answer:
A. They drew political boundaries with little regard for existing ethnic and religious divisions.
Step-by-step explanation:
After World War I, Great Britain and France increased tensions in Southwest Asia by redrawing the political boundaries of the region.
They divided the lands of the former Ottoman Empire into various countries and protectorates, with little regard for the existing ethnic and religious divisions that existed in the region.
This created an unstable political situation, as the arbitrary borders often divided ethnic and religious groups, leading to unrest and conflict.
