Answer:
A. Mark Antony’s life will be spared because he will be useless without Caesar.
Step-by-step explanation:
This is the excerpt from William Shakespeare's play "Julius Caesar".
Although the plotters, at first, think about killing Mark Antony too, as Caesar's close follower ("Let Antony and Caesar fall together"), this decision is later changed.
Comparing Mark Antony to Caesar's limb, metaphorically, they claim that the limb wilk be useless without a head (Caesar) to control it, thus deciding to spare Mark Antony's life ("And for Mark Antony, think not of him, For he can do no more than Caesar’s arm When Caesar’s head is off").
