What is the purpose of the National Do Not Call Registry?

The correct answer highlights the primary function of the National Do Not Call Registry, which is designed specifically to control telemarketing calls made to consumers. This registry allows individuals to add their phone numbers to a list that telemarketers must respect, thereby limiting unwanted sales pitches and promoting consumers' privacy. The overarching goal is to reduce the frequency of unsolicited telemarketing calls, which many people find intrusive and annoying.

The other choices do not align with the primary intent of the National Do Not Call Registry. The process of listing properties for sale pertains to real estate listings and market activity, rather than controlling telemarketing. Similarly, registering new businesses relates to business regulations and incorporation processes, which are unrelated to telemarketing practices. Confirming property ownership involves legal and title aspects of real estate but has no connection to telemarketing efforts or consumer privacy.
