Which of the following is a stage of narcotic detector dog training?

The Indication Skills Stage is a crucial component of narcotic detector dog training. During this stage, the dog learns to exhibit distinct behaviors or signals when detecting the presence of narcotics. Training focuses on refining the dog's ability to communicate its findings to the handler effectively. This may involve alerting through specific behaviors such as sitting, standing, or indicating with their nose.

Understanding this stage is vital for the development of a detector dog, as strong indication skills are necessary for the dog to perform its duties effectively in real-world scenarios, such as searches or seizures. The training emphasizes consistency and clarity in the dog's responses to ensure the handler can recognize and act upon those indications in a variety of situations.

The other options, while potentially relevant in various contexts related to dog behavior or training techniques, do not specifically align with recognized stages in narcotic detector dog training. The focus on indication skills relates directly to the core objective of narcotics detection, making it the most fitting choice.
