The correct answer is involuntary gasping, resulting in water inhalation and drowning.
Involuntary gasping or agonal respiration or gasping respiration refers to an unusual pattern of breathing and brainstem reflex featured by labored breathing, gasping, followed by myoclonus and strange vocalizations.
The feasible reasons may include extreme hypoxia (insufficient supply of oxygen to the tissues), cerebral ischemia, or even anoxia (complete depletion of oxygen).
