Question 4770 Deck General

The correct answer is C) 1S. If the starboard forward inclination is slowly increasing, this indicates that the vessel is listing or tilting to the starboard (right) side. This suggests that a tank on the starboard side of the vessel is likely damaged, causing the vessel to list in that direction. Since the question states that the casing was dropped over the starboard side, the 1S (1 starboard) tank is the most likely tank to be damaged. The other options are incorrect because the 3S (3 starboard) tank is located aft (towards the rear) of the vessel, the 1P (1 port) tank is on the port (left) side, and the 2S (2 starboard) tank is located amidships, not near the area where the casing was dropped.
