The correct answer is "A popular vote margin of fewer than 120,000."
The Presidential election of 1960 was one in which JFK beat Nixon. In this election, JFK received 303 electoral votes and Nixon received 219 (proving the last statement wrong).
Statement one is also incorrect, as Nixon won the state of California. Lastly, statement two, is incorrect as well. This is because Nixon won almost every western state except Nevada.
