How does a consumer differ from a customer?

A) The consumer pays for the product or service.
B) The consumer uses the product or service.
C) The consumer is a repeat purchaser of the product or service.
D) The consumer stays with a particular company for purchase of the product or service.

A customer is someone who buys a product or service from a company, while a consumer is someone who uses or consumes the product or service. In some cases, the customer and the consumer may be the same person, but in other cases, they may be different. For example, a parent may be the customer who purchases a toy for their child, but the child is the consumer who actually uses the toy.
