Which of these is listed as a main difference between consumer and business markets?

1. The main differences are purchase volume, number of customers, location of buyers and direct distribution. 2. On purchase volume, business customers buy in much larger quantities than consumers. 3. On number, business marketers usually have far fewer customers, so option two is reversed. 4. On location, business customers are more geographically concentrated, so option three is reversed. 5. On distribution, business sales tend to go direct rather than through retail, so option four is reversed. _Source: OpenStax Introduction to Business (CC BY 4.0), Ch 11 "Creating Products and Pricing Strategies to Meet Customers' Needs", section 11.4 Buyer Behavior_
