Question 1898 Deck Safety

The correct answer is A) the uppermost deck to which transverse watertight bulkheads extend. This is the correct answer because the regulations define the bulkhead deck as the uppermost deck to which the transverse watertight bulkheads are carried. This is the key structural deck that subdivides the vessel and contributes to its overall stability. The other options are incorrect because B) any deck extending from stem to stern is too broad, C) the uppermost complete deck may not necessarily be the bulkhead deck, and D) the lowermost deck to which bulkheads extend would not be the bulkhead deck.
