The correct term for a sudden loss of brain function due to a disruption of blood supply to the brain is b) Stroke.

A stroke occurs when the blood flow to a specific part of the brain is interrupted, either by a blood clot or a ruptured blood vessel. This interruption prevents oxygen and nutrients from reaching the brain cells, leading to the sudden loss of brain function.

There are two main types of strokes: ischemic stroke and hemorrhagic stroke.

1) Ischemic stroke occurs when a blood clot blocks or narrows an artery that supplies blood to the brain. This type of stroke is more common and accounts for about 87% of all strokes.

2) Hemorrhagic stroke occurs when a blood vessel in the brain ruptures and causes bleeding. This type of stroke is less common but is often more severe and can result in brain damage.

The symptoms of a stroke can vary depending on the part of the brain affected, but they often include sudden weakness or numbness on one side of the body, trouble speaking or understanding speech, dizziness, severe headache, and difficulty walking or maintaining balance.

It is important to recognize the signs of a stroke and seek immediate medical attention as early intervention can help minimize brain damage and improve chances of recovery.
