The Correct Answer is

A. Setting up puppet governments there.

The correct answer is: During the post-war period, the USSR was able to control Poland and Hungary by setting up puppet governments there.

The USSR spread to Central and Eastern Europe, forming a protective buffer zone. The Soviets overran several states setting up communist governments. This buffer area was known as the "iron curtain", the boundary dividing Europe into two separate areas from the end of World War II in 1945 until the end of the Cold War in 1992. In only three years the USSR established people's democracies ruled by Communist parties in both Poland and Hungary.
