Answer:
The correct answer is:
✔️Brutus declares that Caesar must die, though he has nothing personal against him. He worries about how Caesar would change if he were crowned and explains that evil comes from good—much like dangerous snakes can come out on sunny days, when everyone needs to watch where they step. He says that Caesar may do damage if he is crowned.
Explanation:
The correct excerpt from Act 2 Scene I:
Brutus. It must be by his death: and for my part I know no personal cause to spurn at him but for the general. He would be crowned: how that might change his nature, there’s the question. It is the bright day that brings forth the adder,* and that craves wary walking. crown him that, and then i grant we put a sting in him that at his will he may do danger with.
*an adder is a snake
From the above excerpt, it is clear that Brutus doesn't have a personal reason for killing Caesar. But he feels that when Caesar gets the crown, it might change him and give him the power and licence to do damage.
Therefore, last option is the correct answer.
