The correct answer is B) the cargo may shift transversely. A ship with a short rolling period, or "stiff ship" condition, will experience more violent and rapid rolling motions compared to a ship with a longer rolling period. This increased rolling motion can cause the cargo on board to shift transversely, or side-to-side, as the ship rolls. This can be a hazardous condition, as unsecured or insufficiently secured cargo may break free and move across the deck, potentially causing damage to the ship, the cargo, or even endanger the crew. The other answer choices are incorrect. Option A is wrong because the cargo will be affected by the stiff ship condition. Option C is incorrect because the cargo lashings may not be able to withstand the increased rolling forces. Option D is incorrect because the cargo is more likely to shift transversely rather than longitudinally (front-to-back).
