Final answer:
The 'Right to be heard' is the consumer right that includes the ability to make formal complaints. It ensures consumers can voice opinions or concerns regarding products or services, providing a mechanism for redress and feedback.
Step-by-step explanation:
In the context of consumer rights and responsibilities, the question pertains to which right includes the ability to make a formal complaint about a business. Among the listed options, the Right to be heard is the one that encompasses a consumer's entitlement to raise a formal complaint and expect that complaint to receive due consideration by the business, government, or any other institution responsible for consumer protection. This right emphasizes the significance of consumer feedback and assures that consumers have avenues to seek redress or voice their opinions about the products and services they use.
Economics highlights that with personal economic rights, such as the right to safety, the right to be informed, the right to choose freely, also come responsibilities. Among these, using products safely, choosing goods and services carefully, seeking information for informed decisions, and voicing preferences, complaints, or compliments qualify as consumer responsibilities. Hence, speaking up to inform a business about the consumers' likes or dislikes or making formal complaints about issues is an essential aspect of the Right to be heard.
