(B) Russia
Description: The correct answer is B, as Russia vetoed the UN resolution regarding the Strait of Hormuz. Option A is incorrect because India did not veto the resolution. Option C is misleading; while the US is involved in the situation, it was not the one that vetoed. Option D is also correct in that China vetoed, but since the question asks for a single country, B is the best answer. ๐ Pro-Tip: Keep track of international relations for better context!
