The correct answer is answer D ("His plan to withhold punishment from the Central Powers").
The Fourteen Points consisted of a series of settlement principles to push forward peace negotiations that aimed to end World War I. President Woodrow Wilson released a statement regarding peace terms on January of 1918. <u>The purpose behind his speech was to show an intent to punish Germany but recognize that they couldn't realistically pay for damages</u>.
<u>However, Wilson became ill when the Paris Peace Conference took place and this left room for French Prime Minister Georges Clemenceau to contradict Wilson's points significantly</u>. The central point of debate (argued by historians even to this day) was the capability of Germany to pay for damages. Clemenceau took a strong stance claiming that France's industries and welfare had been greatly compromised by German attacks and the Central Powers had to be punished.
Shortages of manpower. That's why in Germany (and many other countries) after the war women were used to clear the streets of rubble. Shortages of accommodation. Bombing raids on cities and towns meant that people who's homes had been destroyed lived in temporary accommodation like army barracks and tents.
