The correct answer is 3. To pay any country fighting against communism.
Step-by-step explanation
After the Second World War in the United States, the Truman Doctrine was adopted to provide support to free peoples who were in resistance against the attempts of communist subjugation. This doctrine was adopted because communism was seen as a threat to the capitalist economic and social system. Due to the above, framed by this doctrine, anti-communist tendencies were promoted that persecuted any movement that called itself the political left. So, the correct answer is 3. To pay any country fighting against communism.
