Option A.

Explanation:

The Soviets declined to allow polls in Eastern European countries, is the right answer.

The distinct discrepancies in the political arrangements of the two nations often stopped them from arriving a mutual agreement on key management matters. However, tensions between the two nations increased when the Soviets declined to concede polls in Eastern European countries.
