Which of the following best describes three in-store retail factors affected by SKU proliferation?

The best description of the three in-store retail factors affected by SKU proliferation is variety, placement, and space. SKU (Stock Keeping Unit) proliferation refers to the increase in the number of distinct products a retailer offers, which has a direct impact on these three specific factors.

Variety indicates the diversity of products available in a particular category. As SKU proliferation increases, retailers offer a wider range of products to meet varying customer preferences. This expanded variety can enhance a customer's shopping experience, as they have more options to choose from.

Placement refers to how products are organized and positioned on the retail floor. With more SKUs, strategic placement becomes crucial to ensure that customers can easily find and access products. This can influence product visibility and the likelihood of purchase.

Space pertains to the physical area allocated to products within the store. As SKUs proliferate, retailers must carefully manage shelf space to accommodate the increased variety. This includes decisions on how much space to devote to each product to optimize sales while maintaining an attractive store layout.

The other options, while relevant to retail, do not directly encapsulate the core factors specifically influenced by SKU proliferation in relation to the in-store environment.
