    Answer : Option A

    Explanation :

    The tissue which allows aquatic plants to float is Aerenchyma. Basically aerenchyma is parenchyma tissue in aquatic plants. The cells of aerenchyma make a network which has wide air spaces or air cavities for gaseous exchange. These air cavities make the plant light and buoyant and hence, plants can float easily in water.
