AI Explanation
The correct answer is A) sealed or lashed closed. According to U.S. regulations, when a tank vessel is discharging cargo, each sea suction valve connected to the vessel's oil transfer, ballast, or cargo tank systems must be sealed or lashed closed. This is to prevent the accidental or unintended discharge of oil or other cargo during the transfer operation. The other options are incorrect because they do not match the regulatory requirement for the sea suction valves to be sealed or lashed closed.
