What is a "fragrance"?

A fragrance is typically defined as a pleasing or sweet olfactory property, often associated with pleasant scents found in flowers, perfumes, and other aromatic substances. This option captures the essence of what people generally consider a fragrance to be—inviting and enjoyable aromas that can enhance an experience or evoke memories. Fragrances can be derived from natural sources, such as essential oils from plants, or created synthetically.

While other options mention aspects of scent, they do not align with the widely accepted definition of "fragrance." For instance, noise is unrelated to olfactory properties, and describing a scent as harsh or unpleasant does not encompass the positive connotation that the term "fragrance" typically carries. Thus, the choice of a pleasingly sweet olfactory property accurately reflects the meaning of fragrance in a way that resonates with common usage and understanding.
