Marketing consists primarily of advertising a product or service.
a. true
b. false

I think the answer would be false. Marketing does not primarily consists of only advertising a product or service. It involves with the buying and selling of a product or a service. It would include advertising, selling of the products and the delivery of these products to the consumers. It should be able to coordinate the 4P's in marketing namely the product, the price, the place and the promotional strategy. So, it is not mainly advertising a product or a service.
