Explanation:

The Watergate scandal was a major political scandal that took place in the United States in the 1970s as a result of a theft of documents in the Watergate office complex in Washington DC, home of the National Committee of the United States Democratic Party, and the subsequent the Nixon administration's attempt to cover up those responsible. When the conspiracy was uncovered, the United States Congress initiated an investigation, but the resistance of Richard Nixon's government to collaborate in this led to an institutional crisis.

i believe the correct answer is option b. most eastern european nations joined nato.

though i could be wrong, option d. the eastern european nations were granted complete independence, would be another choice.

hope this ! : )
