Answer:
The correct answer is A. During an epileptic seizure, a sensory hallucination such as flashes of light, is called an aura.
Step-by-step explanation:
An aura in neurology is the set of usually short-term symptoms that form the start of an epileptic or migraine attack. It is not the same as a prodrome that, as a symptom, announces the development of a disease attack hours to sometimes days before the actual attack, and develops very gradually and dormantly. An aura, on the other hand, develops gradually, but within a few minutes and is much more in the foreground than a prodrome.
Epilepsy patients in whom an aura announces an attack can, thanks to the aura, enter a safe environment to await the upcoming attack.
