When exposed to smoke, hydrogen cyanide may play a role in rendering firemen and bystanders incapable of performing self-rescue.
HCN is a toxin that spreads throughout the body; it is hazardous because it inhibits cytochrome oxidase, which stops cells from using oxygen. Loss of awareness, respiratory arrest, and finally death arise from inhibition of the last stage of electron transport in brain cells.
Higher HCN exposures cause cardiovascular collapse, tremors, cardiac arrhythmia (which may not manifest for two to three weeks after the fire exposure), coma, respiratory depression, and respiratory arrest. Inhaling minute concentrations of hydrogen cyanide can result in headaches, weakness, nausea, and vomiting. Larger doses might result in fainting, convulsions, gasping, fast pulse, irregular heartbeat, and even death. In general, the severity of the symptoms increases with the seriousness of the exposure.

Answer:
C. Officer Friel is employing police discretion.
Explanation:
This particular form of approach by the above policeman in our scenario above is simply explaining about the study of police discretion from this decision making perspective. It is concerned with several forms of authority: stops, frisks and searches, arrests, tickets, and the use of physical force. Police authority is infrequently invoked, as a proportion of all police citizen contacts. Officers consider their authority as a resource in handling such situations, and often they are able to handle situations without resorting to the use of formal authority.
