I say A, panama
Step-by-step explanation:
The Panama Canal is controlled by the Panama Canal Authority, an agency that is part of the government of Panama. When the Canal first opened in 1914, it was controlled by the United States, the country that had led its design and construction. However, as time went on, American control of the canal led to increased tensions between the U.S. and Panama. In 1964, these tensions broke out into riots near the canal zone, today known as Martyrs' Day, in which 22 Panamanians and four U.S. soldiers were killed. Finally, in 1977, U.S. President Jimmy Carter and Panamanian leader Omar Torrijos signed the Torrijos-Carter Treaty, which stipulated that control of the canal would transfer over to Panama in 1999.
