Under the terms of the peace treaty, Germany had to

a. give its colonies independence.

b. pay reparations to the Allies.

c. break up Czechoslovakia.

d. give its tanks and artillery to France.

Germany never really had colonies, so answer a) is not good. but it did have to pay reparations after the second War War (and after the first World War) - answer b is the correct answer.

It would not have to break up Czechoslovakia - as it would also additionally "punish" Czechoslovakia, which did not start the war.
