Answer 1

B. Colombia rejected the U.S. offer to build a canal through Panama.

The primary cause for U.S. military intervention in Colombia in 1903 was related to the United States' interest in building a canal through Panama. After Colombia rejected the U.S. proposal for the canal, the U.S. supported Panama's independence movement, leading to the establishment of Panama as a separate republic and eventually allowing the U.S. to build the Panama Canal.
