XYZ is a business-to-business company that knows the following about its customers.

Since XYZ is a business-to-business company, understanding how customers use their products is the single most important factor in tailoring solutions, marketing, and support. This directly affects customer value and satisfaction.

While geographical regions (B) and employee workforces (C) might influence buying patterns or support needs, those are secondary to how the products are actually used by the customer.

Pricing differences (D) are a result of sales strategies, but they don't inherently impact how the product functions for the customer.
