The correct answer is D. Soldiers could not speak to German citizens
Explanation:
General Eisenhower led and supervised the military operations that were part of the invasion of Germany by the Allies during the Second World War. As part os this, Eisenhower demanded American Soldiers to avoid fraternizing or interacting with German citizens as they were considered the enemy. This was an anti-fraternization policy imposed in the American sector of Germany. However, this policy gradually ended as soldiers were allowed to speak to children and then to adults in certain situations. According to this, the anti-fraternization policy means "Soldiers could not speak to German citizens".
