Assortment offered by a retail store refers to:

The assortment offered by a retail store specifically pertains to the range of products available for sale. This concept encompasses the variety of items that a retailer stocks, including different brands, sizes, colors, and styles. A well-curated assortment allows retailers to meet the diverse needs and preferences of their customers, which can lead to increased customer satisfaction and loyalty.

In retail, having a broad and well-managed assortment is crucial because it enables customers to find the products they are looking for, encouraging them to make purchases. Retailers often analyze market trends to adjust their assortment, aiming to offer products that appeal to different customer segments and to react promptly to changes in consumer demand.

While the other options mentioning payment options, sales strategies, and merchandise display techniques are relevant to retailing, they do not define the term "assortment." Payment options relate to the methods by which customers can complete transactions, sales strategies involve the tactics used to sell products, and merchandise display techniques focus on how products are presented to consumers. Thus, the range of products available for sale is the correct understanding of the term "assortment" in a retail context.
