Step-by-step explanation:
The National Registration Database (NRD) is a database used by Investment Advisors (IAs) to submit registration forms electronically and fulfill regulatory requirements. Statement 3 is true, as the NRD allows IAs to make a single electronic submission for registration. The NRD is not exclusively used for filing registration forms with the TSX, so statement 1 is false. The NRD is also not a paper-based system, so statement 2 is false. Furthermore, the NRD does not directly track money-laundering activities through the banking system, so statement 4 is false.
