Answer:
B. It convinced U.S. leaders to provide more support to foreign anti-communist groups.
Step-by-step explanation:
The shift toward détente influence U.S. foreign policy during the Cold War by "convincing the United States leaders to provide more support to foreign anti-communist groups."
While Detente is a shift from a direct foreign policy of containment by the U.S. to a situation where the U.S. must dialogue with countries based on their strength and not agree with government policies.
Hence instead of the United States going confrontational against the communist nation during the cold war, the Detente policy rather made the United States provide military and economic aid to countries resisting Communist aggression.
