Answer:
A. Descends into madness.
Explanation:
'Macbeth' is one of the greatest and timeless tragedies of Shakespeare. Macbeth is so uncertain about the idea of killing Duncan and after the murder, he is so terrified by intense guilt that almost drives him into madness. He is so perturbed that he brings the bloody daggers with him from the murder scene. He falls into hallucination and dreads that he would be foredoomed to never sleep again and fears that he could never pronounce the word "Amen" and being dam-ned. He begins to believe that blood in his hands would turn the whole sea to red. His madness is led by his distress and it goes up to an extent when he orders the murder of Macduff's innocent wife and children and eventually turned him into a brutal man.
