Step-by-step explanation:
A hemorrhagic stroke (option b) is most likely to cause a coma in a patient.
A hemorrhagic stroke occurs when an artery in the brain ruptures and causes bleeding in the brain. This deprives downstream tissues of adequate blood flow and also puts pressure on brain tissue. Both factors can lead to the death of brain cells. Hemorrhagic strokes are more likely to be fatal than ischemic strokes.
