Final answer:
Undifferentiated targeting is similar to mass marketing in that it targets the broadest number of potential customers without segmentation, appealing to common needs across the market.
Step-by-step explanation:
Among the global target marketing strategies listed, Undifferentiated targeting is most similar to a mass marketing strategy in a single country. Undifferentiated targeting involves creating a single marketing strategy that aims to appeal to the broadest number of potential customers. This approach disregards individual market segments and instead focuses on common needs or characteristics across the market. It is similar to mass marketing in that it treats the market as a homogeneous whole, rather than being segmented into different groups with specific needs or preferences.
