Answer:
b) Duncan is a guest in my house and I should be protecting him, not harming him myself.
Step-by-step explanation:
The translation of the passage from Act I, Scene VII, of "The Tragedy of Macbeth" by William Shakespeare, that best explains Macbeth's reasoning for not murdering Duncan is option b. These lines show that Macbeth is aware that the crime he intends to commit goes against loyalty and hospitality. He says that as subject to the King he cannot kill him because he owes him his loyalty. Secondly as his host, due to hospitality, he should care for his safety instead of killing him.
