• A. Europe: Before World War II
• B. Europe: After World War II
• C. Europe: Since 1990
• D. Russia and the Former Soviet Union

Answer: (C)

Changes in Europe after the Cold War reshaped national borders, showing how political shifts can redraw maps. East and West Germany joined as one country in 1990, unifying a divided Germany and ending decades of separation. At the same time, Yugoslavia broke apart through the 1990s, producing several new independent states and altering the region’s boundaries. These examples all occurred from 1990 onward, illustrating why the appropriate category is Europe: Since 1990. Earlier periods, like before World War II or immediately after World War II, involve different border dynamics, and the events described here specifically reflect post-1990 changes in Europe.
