<span>Macbeth realizes Banquo knows too much about the witches prophecies regarding the kingship
</span>
he appears mentally unstable and guilty of murder
that Macbeth has had such fits since his youth

I think that it is A that it allows him to misbehave
It means to be in low spirits due to loss of courage or hope. Brainliest plz!!!
