Which of the following is not an element of service marketing mix?

Answer: Option B

In service marketing, the service marketing mix typically includes 7 Ps: Product, Price, Place, Promotion, People, Process, and Physical Evidence.

Packaging is not considered a core element in the service marketing mix because services are intangible and do not require physical packaging like products do.

Therefore, Option B is the correct answer as it is not an element of the service marketing mix.
