Final answer:
Hot Coffee employs an undifferentiated marketing approach, which targets the entire market with a single product and marketing strategy, as opposed to differentiated, concentrated, or micromarketing strategies that tailor to specific segments.
Step-by-step explanation:
Hot Coffee, a retail coffee bean business, that designs a single marketing mix and directs it at the entire market is using the undifferentiated marketing approach.
This strategy involves creating a single product and marketing strategy that is intended to appeal to the broadest number of potential customers. Instead of segmenting the market into different groups based on their unique preferences and creating different products and marketing strategies for each group, Hot Coffee treats the market as a homogenous whole.
By comparison, a differentiated strategy would involve the company targeting multiple market segments with separate offerings and marketing strategies, while a concentrated approach would mean focusing on just one niche market.
Micromarketing goes even further, customizing marketing efforts to individual customers or local customer segments.
Therefore the correct answer is 1) Undifferentiated.
