C: Hyperventilation provokes absence seizures
Answer: C: Hyperventilation provokes absence seizures 
Explanation: Answer- C. Hyperventilation provokes absence seizuresTypical absence seizures are characterized by sudden, brief lapses of consciousness without loss of postural control.The seizure typically lasts for only seconds, consciousness returns as suddenly as it was lost, and there is no post ictal confusion.Typical absence seizures are associated with a group of genetically determined epilepsies with onset usually in childhood (ages 4-8 years) or early adolescence.Hyperventilation tends to provoke these electrographic discharges and even the seizures themselves and is routinely used when recording the EEG.
