Final answer:
The Consumers Union primarily reports the quality of products and services to inform consumers, separate from the CPSC which focuses on recall information and safety education. The correct answer is option: b) report the quality of products and services.
Step-by-step explanation:
The main purpose of the Consumers Union is to report the quality of products and services. This organization conducts research, testing, and outreach to ensure that consumers have reliable information about various products and to uphold consumer protection.
While the Consumer Products Safety Commission (CPSC) focuses on providing recall information and safety education about products, and protecting the public from unreasonable risks of injury or death from thousands of types of consumer products, the Consumers Union's role is distinct in that it prioritizes informing the public about product quality through its resources and publications.
