Correct Answer: Option D — 1.90 feet

To maintain the required metacentric height (GM), the VCG of remaining cargo must be restricted. By calculating the vertical moments of the 6 containers stowed on deck and subtracting them from the total allowable moment, the maximum permissible VCG for the remaining cargo is determined to be 1.90 feet.
