Answer:
The correct answer is D. Watergate was the scandal involving a break-in at the Democratic headquarters and President Nixon's cover-up of the incident.
Explanation:
Watergate was a leak, a political scandal and a constitutional crisis in the United States between 1972 and 1974. It led to the resignation of President Richard Nixon. Shortly before the presidential election in 1972, the private aides of then-President Nixon, nicknamed "Plumbers," broke into the rival Democratic Election Office.
Some people working under the President began slowing down burglary investigations. As a result, the press began to dig into the background of the burglary. In 1973, the Plumbers' contact with the Nixon Re-selection Committee was confirmed, further expanding criminal investigations. To protect himself, Nixon dismissed his assistants. To prevent information leaks, he had recorded and archived all White House telephone conversations that had to be released for investigation. A long strip of Nixon's evidence of guilt or innocence had been wiped off the crucial tape. Nixon resigned voluntarily in 1974 and was succeeded by his Vice President, Gerald Ford.
