Answer:
The correct answer is The audience knows all about the plot to kill Caesar, but Caesar himself knows nothing.
Explanation:
Dramatic irony is a typical feature of the tragedy.
In this situation, the audience or the reader has a knowledge about the events that are developing much greater than the information that a character has, in this case Caesar.
<u>Caesar does not even imagine that they are planning to kill him</u>, much less that his best friend and right hand is one of those who plans to do so.
This is clearly demonstrated when he expresses the phrase: <em>"Et tu, Brute?"</em> seeing Brutus among the group of his murderers. With this phrase Caesar shows that he had no idea what was happening and could not even believe how his friend was betraying him.
Therefore, the correct answer is The audience knows all about the plot to kill Caesar, but Caesar himself knows nothing.
