How did Guatemalan policy most affect U.S. interests?

The correct answer is: O U.S. companies owned a large proportion of Guatemala’s land.

Explanation: U.S. interests in Guatemala were significantly impacted by the ownership of land and resources by American companies, particularly in the agricultural sector. This ownership influenced U.S. foreign policy, as the U.S. sought to protect its economic investments and maintain stability in the region during the Cold War era. Consequently, the U.S. government often intervened in Guatemalan affairs to ensure favorable conditions for these companies.
