Which navigation method uses smell cues to locate routes or destinations?

• A. Echolocation
• B. Zugunruhe
• C. Olfactory navigation
• D. Magnetoreception

Answer: (C)

Smell-based navigation relies on olfactory cues to guide movement. Animals use the scents in their environment to build an internal map and follow odor gradients or familiar odors toward routes or destinations, such as home ranges or nesting sites. This makes olfactory navigation the best fit for “uses smell cues to locate routes or destinations.” For context, other navigation methods involve different senses: echolocation uses sound echoes to judge space, magnetoreception relies on Earth's magnetic field, and Zugunruhe is migratory restlessness rather than a smell-based navigation strategy.
