Which compound is responsible for the smell of floral, rose?

Explanation:
Phenylethanol has a rose-like, floral odor, which makes it the best match for the scent of rose. In perfumery, this compound is a classic rose note and contributes that soft, sweet floral quality associated with roses. The other options have different dominant smells: citral gives a lemony, citrus impression; limonene is also citrusy, often orange-like; vanillin provides a vanilla scent.
