The answer is C. That's what happened.
With the support of the U.S. government, Panama issues a declaration of independence from Colombia. The revolution was engineered by a Panamanian faction backed by the Panama Canal Company, a French-U.S. corporation that hoped to connect the Atlantic and Pacific oceans with a waterway across the Isthmus of Panama.
In 1903, the Hay-Herrán Treaty was signed with Colombia, granting the United States use of the Isthmus of Panama in exchange for financial compensation. The U.S. Senate ratified the treaty, but the Colombian Senate, fearing a loss of sovereignty, refused. In response, President Theodore Roosevelt gave tacit approval to a rebellion by Panamanian nationalists, which began on November 3, 1903. To aid the rebels, the U.S.-administered railroad in Panama removed its trains from the northern terminus of Colón, thus stranding Colombian troops sent to crush the insurrection.
