Which type of repellent is described as primarily affecting scent rather than taste?

• A. Taste repellents
• B. Odor repellents
• C. Hair repellents
• D. Chemical repellents

Answer: (B)

Odor repellents deter animals mainly through scent, influencing their olfactory sense before any contact or ingestion occurs. By releasing a smell that animals find off-putting or frightening, these repellents keep them away from the treated area without relying on a bitter taste exposure. In contrast, taste repellents rely on a aversive taste when the animal mouths or chews, affecting the gustatory system rather than smell. Hair repellents depend on tactile or physical cues rather than scent. While some products labeled chemical repellents may include odor components, the description focused on scent rather than taste best fits odor repellents.
