What is the role of canine units in airport security?

• A. To assist passengers with luggage
• B. To detect explosives and illegal substances
• C. To provide companionship to staff
• D. To patrol runways for wildlife

Answer: (B)

The role of canine units in airport security is primarily focused on their ability to detect explosives and illegal substances. Canines are trained to recognize specific scents associated with various explosives and drugs, making them an invaluable asset in security operations. Their keen sense of smell allows them to identify potential threats more effectively than technology alone in many instances. This capability is crucial in maintaining passenger safety and ensuring that prohibited items do not enter secure areas of the airport or onboard aircraft.

While assisting passengers with luggage, providing companionship, and patrolling runways for wildlife may have their own merits in different contexts, these activities do not align with the primary responsibilities of canine units specifically assigned to security roles at airports.
