Which of these is an example of a place decision for a brick and mortar retailer?

The option indicating store size, layout, and design is a clear example of a place decision for a brick-and-mortar retailer. This decision is fundamental to the retailer’s strategy as it directly impacts customer experience and operational efficiency. The physical space of the store plays a crucial role in guiding customers through their shopping journey, influencing how products are displayed, and affecting customers' perceptions of the brand.

A well-thought-out store layout can enhance customer flow, encourage product exploration, and maximize sales potential by strategically placing high-demand items and promotions. Additionally, the design of the space can create an inviting atmosphere that aligns with the brand's identity, which is essential for attracting and retaining customers.

The other options pertain to different aspects of retail decision-making. Pricing relates to the value proposition and competitive positioning rather than the physical environment. Advertising campaigns focus on promotion and communication strategies. Customer service policies define how employees interact with customers, but they are not related to the physical "place" aspect of retailing. Thus, focusing on store size, layout, and design accurately reflects the essence of place decisions in the context of brick-and-mortar retailing.
