The correct answer is A) Kaiser Wilhelm had to abdicate its throne.
When Germany offered to surrender, President Wilson would not agree to it unless something happened first. This was the abdication of Kaiser Wilhelm.
He was the Emperor of Germany and King of Prussia. He had to abdicate his throne on November 28, 1918, after the Central Powers had been defeated by the United States, France, Great Britain, and Russia. Germany had fought during World War 1 with the Austria-Hungary and the Ottoman Empire, the so-called Central Powers. Wilhelm had ruled Germany and Prussia since June 15, 1888. He was the last emperor of Germany.
