    Agreed. The best answer is D.

    A "tender" vessel is one with a relatively small GM and a relatively long rolling period.

    If G is raised to M the vessel will have neutral initial stability and appear to stay where ever you put it.

    If G is above M the vessel is initially unstable and will not remain upright and will flop to either side. The rolling period formula is based on SIMPLE HARMONIC MOTION or Pendulum Stability. If the GM is negative you will not be able to calculate the rolling period because you cannot take the square root of a negative number.

    T=0.44(Beam in feet)/(Square Root of GM)

    D. The GM would be lowest in this condition. Could possibly be in angle of lull.
