In which market strategy do companies produce multiple versions of a product to meet individual customer needs?

The strategy where companies produce multiple versions of a product to meet individual customer needs is known as one-to-one marketing. This approach emphasizes personalization, allowing businesses to tailor their offerings to meet the specific preferences and requirements of individual customers. This customization can include different product features, variations, and even dedicated services, all aimed at providing a unique experience that resonates with each customer.

In contrast, mass marketing focuses on targeting a broad audience with a single product offering, minimizing personalization to reach the largest market possible. Niche marketing involves targeting a specific, defined segment of the market, but it doesn't necessarily involve creating many different versions of a product for individual needs. Demographic marketing segments the market based on demographic factors like age, gender, and income but does not specifically address individual preferences through product variations.

Overall, one-to-one marketing stands out because it prioritizes individualized customer experiences, making it the correct response in this context.
