Which group of animal senses is responsible for detecting odors?

The olfactory group of animal senses is specifically responsible for detecting odors due to the specialized structures and receptors involved in the process of smell. Animals possess olfactory receptors located in their nasal cavity that can identify various chemical compounds present in the air. These receptors send signals to the brain, allowing the animal to interpret and respond to different scents.

This sense of smell is crucial for many animals, aiding in behaviors such as finding food, detecting predators, and recognizing mates. The olfactory system's complexity varies among species, with some animals, like dogs, having a highly developed sense of smell that allows them to detect even the faintest odors.

Other sensory groups, such as auditory, tactile, and visual, are responsible for hearing, touch, and sight, respectively, and do not play a role in odor detection. Therefore, the olfactory group is distinct and essential for the sense of smell, making it the correct answer to the question.
