Answer:
The correct answer is D) Created Economic Sanctions which have hurt Russian economy
Step-by-step explanation:
After the Ukrainian revolution of 2014, the pro-Russian president was thrown out of power. As the Parliament was thronged by Pro-European supporters, he fled to the coastal region of Crimea.
The area is known for having traditionally closer ties to Russia than Ukraine itself.
As the ex-President reached Crimea, Vladmir Putin sent in Russian forces to annex Crimea and make him the President of the new 'Republic of Crimea'
European Union and the United States responded by unleashing tough sanctions against Russia to punish it for what they believed was an unlawful grab of land.
