This is not a purpose of marketing:

Opening a checking account is not a purpose of marketing because it pertains specifically to banking services and financial transactions rather than the strategies and tactics used to promote products and services in the market. Marketing is primarily concerned with activities that facilitate the promotion and sale of products, understanding customer needs, and fostering relationships that lead to brand loyalty.

In contrast, promoting a product involves conveying its benefits to consumers to drive sales, identifying customer needs is essential for tailoring products to fit market demands, and building brand loyalty creates lasting relationships with customers, encouraging repeat purchases. All these activities align with the core purposes of marketing, which focus on creating interest and demand for goods and services.
