Which law allows consumers to register their phone numbers to avoid telemarketing calls?

The correct answer is the Telemarketing Sales Rule. This law was established to address the growing concerns surrounding the intrusive nature of telemarketing calls and to provide consumers with a mechanism to reduce unwanted telemarketing contact. Under this rule, the Federal Trade Commission (FTC) has implemented regulations that allow consumers to register their phone numbers on a "Do Not Call" registry. By doing so, consumers can effectively prevent telemarketers from calling them, creating a more controlled and respectful communication environment.

The Telemarketing Sales Rule not only enables consumers to opt-out of unsolicited calls but also imposes specific obligations on telemarketers, such as maintaining their own do-not-call lists and honoring the requests of consumers who wish not to receive calls. This reinforces consumer rights and helps protect personal privacy in communications.

The other options listed pertain to different areas of consumer protection and privacy regulations but do not specifically address the regulation of telemarketing calls in the same way that the Telemarketing Sales Rule does.
