How serious are the complications of a second impact syndrome (SIS)

The correct answer is C. Second impact syndrome happens after a person suffers a second concussion before symptoms from an earlier concussion have subsided. Sometimes a trivial, second head injury can lead to swelling of the brain which can very often be fatal or lead to severe disability. Answers A and B are incorrect because even though it is rare SIS has a high very mortality rate.
