Solution

The correct option is B Gas vacuole
Large vacuoles are found in filamentous sulfur bacteria. The cytosol is extremely reduced in these genera and the vacuole can occupy between 40-98% of the cell. The vacuole contains high concentrations of nitrate ions and is therefore thought to be a storage organelle. Gas vacuoles, which are freely permeable to gas, are present in some species of Cyanobacteria. They allow the bacteria to control their buoyancy.
Therefore, the correct answer is option B.
