Final answer:
The gag reflex typically should return within 1 day after suppression or absence; 3 days may be possible in certain cases. A prolonged absence of the gag reflex beyond this period warrants medical evaluation. The correct option is B).
Step-by-step explanation:
The gag reflex, or pharyngeal reflex, is an automatic throat closure that happens when the back of the throat is touched. The absence or suppression of the gag reflex could occur due to various reasons such as neurological disorders, certain illnesses, or after anesthesia for surgery.
Generally, if the gag reflex is not present, it should return within a day (A 1 day). If the gag reflex does not return within this period, it is advisable to seek medical attention, as it may indicate an underlying health issue.
In few cases, it might take up to 3 days (B 3 days) for the gag reflex to come back, but anything beyond that is not considered normal without medical advice. Option B) is the correct one.
