A vessel sailing from Liverpool to New York puts into Boston, Mass. for emergency repairs. If no inward foreign cargo is to be discharged at that port, which of the following documents is required?

Correct Answer: Option C — Pro Forma Manifest

A Pro Forma Manifest is required when a vessel enters a U.S. port for emergency repairs or bunkers without discharging foreign cargo. This document serves as a temporary declaration to Customs, ensuring the vessel remains in compliance with entry requirements while not engaging in commercial activity within the United States.
