Step-by-step explanation:
The correct answer is A. Marketing. Marketing is the set of operations used by most organizations to reach their customers' goals. It involves understanding customer needs, creating products or services that meet those needs, promoting and communicating the value of those products or services, and delivering them to customers.
For example, a company might conduct market research to determine what customers want, develop a marketing strategy to target those customers, design advertisements to promote their products, and use various channels such as social media, television, or direct mail to reach their target audience and attract customers.
