The correct answers are: Omnichannel + Store Centric, Omnichannel and Store-Centric

Explanation: Navigating the retail landscape requires leveraging Online-to-Offline (O2O) strategies, notably omnichannel, store-centric, or their potent combination. Omnichannel focuses on holistic sales, integrating various channels for a consistent shopping journey. Conversely, the store-centric model zeroes in on offline sales, emphasizing interactions with local customers, resulting in increased footfall and profitability due to higher in-store order values. For a dynamic approach, merging both strategies caters to diverse customer bases, allowing flexibility as sales objectives shift with changing seasons.
