The best answer to the question is (B) services are intangible activities.

Unlike products, services are intangible activities, which makes it difficult for potential customers to know whether a service would be good or not before purchase. It's very easy for customers to feel like they can't tell the quality of service prior to transaction - which is a challenge that a service provider would face and needs to manage.
