Answer:

C. a disruption of blood flow in the arteries going to the brain

Explanation:

A stroke occurs when blood supply to brain is interrupted or reduced. This deprives oxygen and nutrients to be supplied to the brain, causing brain cells to die.  Some people may experience only a temporary disruption of blood flow to the brain. This condition is life-threatening and should be treated immediately.
