What role does the SEC play concerning identity theft?

The correct answer reflects that the SEC, or the Securities and Exchange Commission, plays a crucial role in protecting investors and ensuring that the securities markets operate fairly. This responsibility involves regulating the securities industry, which includes overseeing stock exchanges, brokers, and investment advisors. By enforcing securities laws and regulations, the SEC works to prevent fraud and maintain transparency in the market.

In the context of identity theft, the SEC's activities are vital because fraudulent practices can lead to identity theft and financial loss for investors. The SEC seeks to provide a level of trust and security within the financial markets, which ultimately helps to safeguard investors' identities and personal information against misuse.

The other choices illustrate functions that are not within the SEC’s scope. For instance, consumer debt resolution is typically managed by agencies focused specifically on consumer financial protection, while the Do Not Call Registry is administered by the Federal Trade Commission (FTC). Additionally, the provision of credit scores is handled by credit reporting agencies rather than the SEC. Thus, the role of the SEC in protecting investors and ensuring market fairness is distinctly different and appropriately aligns with the responsibilities it holds in the financial sector.
