Answer :
To answer this question, we need to consider the historical context of the Nixon Watergate scandal and the options given:
a) While Nixon did engage in illegal activities as part of the Watergate scandal, he was not formally removed from office by impeachment or any other legal action by the government. Instead, he resigned before such action could take place. So this is not the best example.
b) Richard Nixon was not sent to jail. Following his resignation, he was pardoned by his successor, President Gerald Ford. Thus, this choice does not accurately reflect the historical events.
c) This choice effectively encapsulates the impact that public opinion can have on the government. As the Watergate scandal unfolded, and as more of the public learned about Nixon's actions and the extent of the cover-up, public support for Nixon waned significantly. This loss of support from the American people was a significant factor that led to his decision to resign from office.
d) It is true that the media played a critical role in uncovering the facts of the Watergate scandal, and in this sense, they put significant pressure on Nixon's presidency. However, stating that Nixon was "forced" to resign by the media is an oversimplification and does not acknowledge the role that public opinion and loss of political support played in his decision.
After evaluating the options, the best example of how the Nixon Watergate scandal demonstrated the impact that people can have on the government is option (c) Nixon lost the support of the American people and resigned. Public opinion and the reaction of the American people, as it became clear that Nixon was involved in the Watergate scandal and engaged in obstruction of justice, played a significant role in his eventual decision to resign from the presidency.
