Which of the following statements is CORRECT? U.S. lawmakers

U.S. lawmakers have criticized the recent US-North Korean deal calling for freezing Pyongyang’s nuclear program in return for US diplomatic and economic concessions. They express concern that the North may take the concessions and break the accord. Other lawmakers noted that inspection of Pyongyang’s nuclear site is not required for at least five years. The U.S. chief negotiator defended the accord, saying he had made no compromise that would damage U.S. national security.
