| The correct answer is A) maintain good stability. Excessive free surface, which occurs when a liquid cargo tank is only partially full, should be avoided to maintain a vessel's stability block blast. This is because the liquid's movement inside the tank, known as the free surface effect, significantly reduces the ship's stability. |
