Reference Answer

The correct statement is **(a) It is used to indicate the quality of initial stability.**
### Justification of the Correct Answer
**(a) It is used to indicate the quality of initial stability.**
This statement is fundamentally correct. The Metacentric Height (GM) is the primary quantitative measure of a vessel's initial stability, which is its tendency to return to the upright position after being heeled by a small external force (typically for angles up to 10-15 degrees).
