Answer: The right answer is the B) obstruction of justice and perjury.
Explanation: Article 2, Section 4 of the U.S. Constitution states: "The President, Vice President and all Civil Officers of the United States, shall be removed from Office on Impeachment for, and Conviction of, Treason, Bribery, or other high Crimes and Misdemeanors." On December 19, 1998 the House of Representatives impeached President Bill Clinton, since he had denied his extramarital affair with Ms. Lewinsky (lying under oath is known as perjury) and had allegedly asked her to declare that they had not had an affair, in order to prevent further investigations (obstruction of justice). Nevertheless, he was eventually acquitted, since a majority was not achieved in the Senate.
