The correct answer is C)  He believed that the wall’s removal would signal a new era of freedom.

President Reagan called for Soviet leader Gorbachev to “tear down” the Berlin Wall because he believed that the wall’s removal would signal a new era of freedom.

US President Reagan considered that the Berlin Wall represented many of the problems that identified the Cold War years and the pain of Germany people from having that division. The wall represented that old way to resolve things that were not needed in the modern and democratic world. Finally, the Berlin Wall was torn down on November 9, 1989, two years after Ronald Reagan's comments to Gorbachev.
