Which of the following provides consumer protection against unwanted solicitation?

The National Do-Not-Call Registry is a tool specifically established to provide consumers with protection against unwanted telemarketing calls, which includes solicitations from mortgage lenders and other businesses. When individuals register their phone numbers on this list, telemarketers are prohibited from calling those numbers, thereby reducing the likelihood of receiving unsolicited offers.

In contrast, the other options focus on different aspects of consumer protection or regulatory requirements. The TILA Trigger Terms Database pertains to specific terminology related to the Truth in Lending Act (TILA) and does not address unsolicited communications. The National Mortgage Licensing Registry is primarily concerned with licensing information for mortgage professionals and does not play a role in protecting consumers from solicitation. Several HMDA databases relate to mortgage lending practices and demographic data but do not address consumer protection against unwanted solicitations either.
