For an immersed neutrally buoyant body to be in stable equilibrium, the center of gravity of the body is directly
Answer: D
The centre of gravity must be below the center of buoyancy.
For a fully immersed body the centre of buoyancy, the centroid of the displaced volume, stays fixed relative to the body as it tilts, so the metacentre coincides with it. A small tilt then creates a restoring couple only if the weight acts below the buoyant force, that is if G lies directly below B.
With G above B the couple overturns the body. The metacentre conditions (G below or above M) apply to floating bodies, whose waterplane area lets B shift as they heel.
