Final answer:
The correct answer is option c. Enhanced freedom and unity.
Step-by-step explanation:
According to President Reagan, the effect of removing the Berlin Wall would be enhanced freedom and unity in Europe. Reagan's 1987 speech at the Brandenburg Gate in West Berlin, issued a call to Gorbachev to "tear down this wall," signifying a desire to end the physical and ideological divide that the Wall represented.
Although Reagan himself did not claim to be the architect of the Wall's eventual destruction, he supported policies and engaged in diplomatic relations that contributed to creating a context in which the fall of the Berlin Wall would become possible. This effort facilitated the reunification of Berlin and Germany and was a significant step in the decline of Communist control in Eastern Europe, symbolizing the end of the Cold War.
