Your vessel is boarded for a Port State Control (PSC) inspection and the PSCO identifies deficiencies serious enough to warrant detention. As Master, what is the correct understanding of the relationship between flag state and port state authority here?
A. The Master can refuse the detention by presenting valid flag-state certificates, since those certificates are conclusive proof of compliance
B. The port state, exercising jurisdiction under conventions such as SOLAS, MARPOL and MLC (and regional regimes like the Paris MOU), may detain the vessel in its port if deficiencies are serious enough to render the ship unseaworthy or non-compliant — independent of the flag state's own certification, though the flag state should be notified and is typically involved in resolving the detention
C. PSC has no authority over a foreign-flagged vessel — only the flag state administration can detain a ship
D. Detention by PSC automatically voids the vessel's flag registration

A. The duty to render assistance to persons in distress at sea overrides immigration status considerations at the point of rescue; the Master must rescue and provide for their safety, while disembarkation arrangements and any immigration questions are a separate matter to be coordinated afterward with flag state, coastal state authorities and the company/DPA
B. The duty to render assistance does not apply if the persons are suspected irregular migrants — the Master may legally ignore them and continue on passage
C. The Master may only render assistance after receiving written authorisation from the company
D. Rendering assistance is discretionary and depends on whether the vessel has spare cabins
