An inclined semisubmersible with a very short rolling period about a constant angle of list is likely to have __________.

Correct Answer: Option A — an off-center TCG

An inclined semisubmersible maintaining a short rolling period paired with a constant list angle experiences a permanent offset in its center of gravity. An off-center Transverse Center of Gravity (TCG) creates a constant heeling moment regardless of dynamic stability fluctuations.
