单选题Your vessel was damaged and initially assumed a significant list and trim; however，further increase has been slow. Based on this data，what should you expect?（）A
The slowing is only temporary and the vessel will probably suddenly capsize or plunge from loss of stability due to change in the waterplane areaB
The vessel can probably be saved if further flooding can be stoppedC
The vessel will continue to slowly list and/or trim due to the free surface effect and free communication effectD
The vessel will suddenly flop to the same or greater angle of list on the other side and may capsize
