Correct Answer : Option (A) - US
Note : The U.S. State Department has cleared $314 million in possible sales of air defense missiles to South Korea as tensions re-emerge on the Korean peninsula. South Korea, a key Asian ally of the United States, asked to buy up to 94 SM-2 missiles used by ships against air threats, along with 12 guidance systems and technical assistance for a total cost of $313.9 million. The U.S. Defense Security Cooperation Agency (DSCA), a unit of the Department of Defense, delivered certification notifying Congress of the possible sale. South Korea already uses SM-2 missiles developed by Raytheon Co but is building more missile defense-capable destroyers equipped with the weapon.
