Final answer:
The current Sergeant Major of the Marine Corps is Troy E. Black. He took office on July 26, 2019, and is the 19th individual to hold this position. The names listed in the question are historical figures and do not correspond to the current Sergeant Major.
Step-by-step explanation:
The current Sergeant Major of the Marine Corps is not among the options provided in the question, which include General George Washington, Brigadier General Daniel Morgan, Major Benedict Arnold, and Major General Benjamin Lincoln. These individuals are notable figures in American history, specifically during the time of the Revolutionary War.
