Which word describes something having a pleasant odor?

The word "fragrant" specifically refers to something that emits a pleasant odor or fragrance. It is often used to describe flowers, perfumes, and food that have appealing scents. The root of the term is associated with the notion of pleasing smell or aroma, making it the most accurate choice when discussing something that is characterized by a delightful scent.

The other terms do not relate to pleasant smells. "Flop" refers to a failure or lack of success, "flaunt" means to display something ostentatiously, and "forage" relates to searching for and gathering food or provisions. Thus, "fragrant" stands out distinctly as the correct answer in the context of describing something with a pleasant odor.
