Read the excerpt from act 3, scene 4 of The Tragedy of
Macbeth
Macbeth. Then comes my fit again: I had else been
perfect;
Whole as the marble, founded as the rock,
As broad and general as the casing air:
But now I am cabin'd, cribb'd, confin'd, bound in
To saucy doubts and fears. But Banquo's safe?
First Murderer. Ay, my good lord; safe in a ditch he
bides,
With twenty trenched gashes on his head;
The least a death to nature.

What does the murderer mean by the phrase "safe in a
ditch?

O Banquo has run away.

O Banquo has attacked them.

O Banquo has been slain.

O Banquo has gone into hiding.
