which of the following is the best example of a sanction?\ncountry a decides to form an alliance with country b.\ncountry a enacts trade restrictions against country b.\ncountry a launches warships toward country b.\ncountry a denies aid money to country b.
Answer
Brief Explanations:
Sanctions are penalties or restrictions imposed on a country, often in the economic - trade sphere. Trade restrictions are a common form of sanctions. Forming an alliance is not a sanction. Launching warships is more of a military action. Denying aid money can be a form of pressure but is not as typical a sanction as trade restrictions.
Answer:
Country A enacts trade restrictions against country B.
