Answer :
In the scene where Macbeth and Banquo were revealed with the prophecy that Macbeth shall be King and that Banquo's children will also be kings, Banquo's response to the witches' prophecy was doubtful and full of suspicion. It implied that they must not believe too much, for they might fall to their demise.
I believe the correct answer is 1-Banquo is wise enough to understand that the witches represent evil.
The witches have prophesied that his children would be rulers, and even though he would like that to happen, he understands that the witches are evil and should not be trusted. He also saw that Macbeth believes them completely which unfortunately led him to his demise.
