Final answer:
Omnichannel retailing focuses on a seamless customer experience across different channels by integrating them, unlike multichannel retailing, which uses multiple channels without necessarily integrating them.
Step-by-step explanation:
Between multichannel and omnichannel retailing, it is omnichannel that places the focus on creating a seamless customer experience across various channels. While multichannel retailing simply means using multiple channels to engage with customers (like in-store, online, phone, etc.), omnichannel retailing goes a step further. It not only uses multiple channels but also ensures that these channels are tightly integrated, allowing for a consistent and seamless customer journey, regardless of the channel or device the customer chooses to use for interaction.
