Services are intangible. This means that a. they have no physical form. b. their availability must match their demand at a specific time. c. they cost more than products. d. there will be differences in the type and quality of service provided.

The correct answer is a. Services are intangible, which means they have no physical form. Unlike physical products, services cannot be touched or seen. They are actions or activities that are performed for a customer, such as providing a haircut, teaching a class, or repairing a car. The intangible nature of services means that they cannot be stored, transported, or owned in the same way as physical goods.
