Which of the following individuals was listed among the eight people put on trial for Lincoln's assassination?

• A. Samuel Mudd
• B. Mary Surratt
• C. Edman Spangler
• D. John Wilkes Booth

Answer: (B)

The question is about who was among the eight people indicted and tried by a military commission for conspiring to assassinate Lincoln. Mary Surratt fits this role because she owned the boardinghouse where Booth and several co-conspirators met, and she was charged with participating in the conspiracy. She was found guilty and hanged, making her one of the clearest examples of someone listed among the eight who faced trial.

Other indicted individuals included Dr. Samuel Mudd, who was convicted and sentenced to life in prison, and Edmund Spangler, who was tried and acquitted. John Wilkes Booth, the actual killer, was not tried because he died during his escape.
