Answer:
I believe your answer is C.
Step-by-step explanation:
Banneker build his clock in 1752, the Civil war was in 1861, WW2 was in 1939 – 1945, The Revolutionary war was in 1775, and George Washington became president in 1789. I think that C is the only reasonable answer. Please let me know if I am wrong (sorry if I was incorrect). Good luck! :))
