URGENT!! will mark brainliest if correct!

Read the excerpt from act 2, scene 1, of Julius Caesar.

[BRUTUS.] And for Mark Antony, think not of him,
For he can do no more than Caesar’s arm
When Caesar’s head is off.

How does this example of dramatic irony affect the audience?

It makes Brutus seem honorable.
It heightens suspense because Mark Antony is dangerous.
It makes Cassius look weak and indecisive.
It heightens suspense because Brutus is dangerous.
