Answer:
B. Sniffer dogs
Read Explanation:
Dedicated Search and Rescue (SAR) teams frequently use search dogs, also known as K-9 units, to detect human scent under rubble.
Why Search Dogs are Indispensable
Superior Sense of Smell: A dog's sense of smell is vastly superior to a human's. They can detect the faintest traces of human scent, even when a person is buried under layers of concrete, debris, or soil. They are specifically trained to differentiate between the scent of a living person, a deceased person, and other animals.
Mobility and Agility: Search dogs are agile and can navigate treacherous terrain that is inaccessible to heavy machinery or even human rescuers. Their ability to squeeze into small spaces and climb over unstable rubble makes them ideal for quickly and efficiently searching a large, collapsed area.
Instant Alert System: When a search dog detects a human scent, it is trained to give a specific signal to its handler, such as barking, digging, or staying put at the location. This immediate alert allows the SAR team to pinpoint the exact location of a victim, saving critical time.
Emotional and Physical Resilience: Search dogs are trained to work in stressful and chaotic environments, with distractions like loud noises and shifting debris. Their unwavering focus and emotional resilience make them a reliable asset in the most challenging of circumstances.
