Briefly Justify Your Answer (16)

Reference Answer

The correct answer is **(b) list until the center of buoyancy is aligned vertically with the center of gravity**.
### Detailed Justification (Surveyor-Grade Explanation)
This answer is based on the fundamental principles of transverse stability. Adding a weight to one side of a vessel introduces an internal, permanent change to the vessel's weight distribution, resulting in a permanent angle of inclination known as a 'list'.
