Answer:
C. He wore civilian clothes rather than uniforms or royal attire.
Step-by-step explanation:
George Washington was a very humble and down to earth person who didn't want to see himself as anything higher than a normal civilian person. So instead of wearing anything that would see himself as anything royal or luxurious he didn't want. Which is why now a President or anyone working in politics wears a normal Business suite to better relate to the American people, rather than having them see them as better than the normal person.
