Which category is not included under the Estidama practices related to retail?

The correct choice reflects an understanding of how Estidama practices are categorized specifically for retail environments. Estidama, which translates to "sustainability" in Arabic, is aimed at reducing environmental impacts and improving efficiencies in various sectors, including retail. While supermarkets and department stores are common types of retail operations that are directly addressed within Estidama practices, warehouse-type retail developments do not typically fall under the same category.

Warehouse-type retail developments primarily serve as storage facilities and distribution centers rather than as end-user retail spaces. Their focus often lies in logistics and supply chain efficiency instead of direct consumer interaction, making them less relevant to the principles of Estidama that target retail experiences focused on sustainability in consumer-facing businesses. Travel agencies also do not operate within the traditional scope of retail as defined by Estidama, which emphasizes physical retail spaces that engage directly with consumers. Thus, the inclusion of supermarkets and department stores makes sense within Estidama practices, while warehouse-type developments do not align with this focus.
