I believe the correct answer is: A) honor.
These lines from Mark Antony’s speaks speech after Brutus’ death in William Shakespeare’s tragedy “The Tragedy of Julius Caesar”, exemplifies the theme of honor of Brutus’ life best.
As we can see in these lines, Mark Anthony acknowledges the fact that Brutus was one of the conspirators of the death of Julius Caesar, but put an emphasis that it was not just betrayal or greed that motivated him, but the saving of the Rome from Caesar’s tyranny. He emphasis his honor calling him “noblest Roman of them all”, adding that his life was gentle.
