The correct answer is D. Great Britain and France taking no military actions after Germany invaded the Rhineland.
Explanation
The appeasement policy was a political position of the United Kingdom that was characterized by being conciliatory towards Germany to keep the peace. This caused the German Nazi regime to violate different international treaties that prevented it from carrying out military actions such as the militarization of the Rhineland, forming an army, interceding in the Spanish Civil War, among others. However, Germany did this military action without the United Kingdom or France having military retaliation against Germany. According to the above, the correct answer is D. Great Britain and France taking no military actions after Germany invaded the Rhineland.
