The correct answer is A) the development of the strategic defense initiative.
The best example of how Reagan dealt with the Soviet Union from a position of strength was the development of the strategic defense initiative.
One of the most important initiatives of President Ronald Reagan was the Strategic Defensive Initiative, better known as SDI. The goal was simple: to shoot down any missiles in space, coming from the Soviet Union or any US enemy. Later, the program was known as Stars Wars. The idea of President Reagan was to be a step ahead of the Soviet leaders and built a space shield that could protect the United States.
