A dentist decides to offer teeth whitening services to a target market. The dentist's marketers have to consider which characteristic of service in their marketing plans? A. marketability B. variability C. inseparability D. intangibility

D) intangibility

Explanation:

in this case, the whitening service offered by the dentist has an intangible characteristic since there is no tangible product or service that their potential customers can see, touch, taste, hear or smell. The service offered is something that the potential customers must imagine, i. e. they have to imagine how they would look like if their teeth were whiter.
