Which of the following represents a concept in consumer behavior?

The concept of a target market is crucial in understanding consumer behavior, as it refers to a specific group of consumers identified as the recipients of a marketing campaign. Marketers analyze various demographic, psychographic, and behavioral factors to define a target market effectively. This allows businesses to tailor their products, services, and messaging to meet the specific wants and needs of these consumers, thereby increasing the likelihood of a successful purchase.

In contrast, while illusion, style, and dress code pertain to aspects of appearance and perception, they do not directly encapsulate the broader strategic approach that marketers take to engage with consumers. Illusion might touch on perception in marketing, style can refer to personal preference, and dress code relates to expectations of attire in certain contexts, but none of these terms encompass the strategic identification and understanding of groups of consumers like target market does.
