In a state-law practice set, a candidate reviews the following scenario. The exam wants the best state-securities answer, not a practical business answer. Registration by coordination under the Uniform Securities Act requires that a security be registered simultaneously with which federal agency?

Why A — The Securities and Exchange Commission (SEC)

Under USA Section 303, registration by coordination is available when a registration statement has been filed with the SEC under the Securities Act of 1933. The state registration becomes effective simultaneously with the federal registration, streamlining the process for issuers conducting multi-state offerings. This variant keeps the same legal rule but shifts the setup so recall has to stay flexible.
