Question

the treaty of versailles forced germany to
join the league of nations
become part of france.
accept responsibility for the war
provide better treatment of its colonies

Explanation:

The Treaty of Versailles held Germany accountable for World War I. Germany was not forced to join the League of Nations (in fact, it was excluded initially), nor to become part of France, and the treaty focused on war guilt and reparations rather than colony treatment improvement. So the correct option is the one about accepting responsibility for the war.

Answer:

C. accept responsibility for the war
