The correct answer is B) The United States was immediately prepared to send a large army to Europe.

The statement that is not true about American preparedness for World War I is " The United States was immediately prepared to send a large army to Europe."

The United States Army was not completely prepared before entering World War 1. Compared to other armies of the time, the US Army was not one of the best. European countries had armies with more experience due to the many conflicts they had been faced in the past.  

That is why some actions needed to be taken such as President Woodrow Wilson signed into law the Selective Service Act on May 18, 1917, in order to recruit and prepare more soldiers to join the Army. This action made possible the enrollment of nearly 10 million Americans. American troops also received instruction from French and British military offices.

The United States was immediately prepared to send a large army to Europe.

Explanation:

When the United States got involved in World War I, the country was not prepared to send a large army to Europe. The United States declared war on Germany on April 6, 1917. Up to this point, the country had remained neutral, although it had contributed to the war as a supplier for the allies. However, when the country started sending soldiers, the effort was initially very modest. It took a major expansion of the United States government for the army to reach the necessary size to make a significant contribution to the war. This was achieved by the spring of 1918.
