Answer A is false: Washington never got to live in the White House, and one of the things he warned about in his Farewell Address was the formation of political parties.
Answer B: There is no evidence to support that he wore his general's uniform. His cabinet only consisted of two of his former officers Alexander Hamilton and Henry Knox. His reasoning for selecting them was not because they were his former officers but because of their expertise.
Answer C: He only served 2 terms, so this answer choice is also false.
Answer D: This is the most plausible answer. Even when Washington got re-elected for his 2nd term, he did not want to be President.
