Step-by-step explanation:
The correct answer is D. A and B.
Marketing is an integrated activity that involves generating and facilitating exchange. It is not equal to selling, as it encompasses a much broader range of activities, such as market research, product development, pricing, promotion, and distribution.
For example, when a company conducts market research to identify consumer needs and preferences, develops a product that meets those needs, determines an appropriate price point, promotes the product through advertising and other means, and makes the product available to consumers through various channels, it is engaging in marketing.
