Final answer:
The correct answer is a) Sensation; perception. Sensation is the detection of environmental stimuli by sense organs, while perception is the brain's interpretation of these stimuli.
Step-by-step explanation:
Information from the environment that is picked up by our sense organs is called sensation, and the meaning that our brain attaches to that information is called perception. Therefore, the correct answer to the student's question is a) Sensation; perception. Sensation involves the sensory receptors detecting stimuli, while perception is the process by which the brain interprets these stimuli. For instance, when you walk into a kitchen and smell the scent of baking cinnamon rolls, the receptors in your nose detecting the odor is the sensation. The recognition and interpretation of that scent, perhaps reminding you of your grandmother's baking, is your perception.
