Ans. 3) smelling cookies in the oven

This expression, fetching cookies out of the oven, indicates olfaction, one of them senses. Olfaction represents the process when chemical substances in the air (odorants) are sensed by a special group of receptors placed inside the nasal cavity, assisting us in identifying various odors as well as scents. The scent of freshly baked cookies is an inseparable part of the baking process. While the cookies are in the oven, the accumulation of volatile compounds in the air increases the flow and activates the olfactory receptors in the nasal cavity, the resulting signals of which we perceive as the scent of the freshly baked cookies. The above other options, e.g., temperate air, tasting happenings, or perceiving your body moving and yourself being stationary, have nothing to do with the sense of smell; the sense of smell is only connected to smellings and sensations.
