The increase in meta centric height i) increases stability ii) decreases stability iii) increases comfort for passengers iv) decreases comfort for passengers The correct answer is A. (i) and (iii) B. (i) and (iv) C. (ii) and (iii) D. (ii) and (iv)

The correct answer is A. (i) and (iii).

Metacentric height is the distance between the metacenter and the center of gravity of a ship. It is a measure of the ship’s stability. A higher metacentric height means that the ship is more stable and will return to its original upright position more quickly after being disturbed.

A higher metacentric height also means that the ship will be more comfortable for passengers. This is because a more stable ship will experience less rolling and pitching motion.

However, there is a limit to how high the metacentric height can be. If the metacentric height is too high, the ship will become unstable and may capsize.

Therefore, the correct answer is A. (i) and (iii).
