B Correct answer
Explanation

Aerenchyma is a type of parenchyma tissue found in aquatic plants that contains large, interconnected air cavities. These air spaces store gases and provide buoyancy, allowing the plant to float or remain upright in water. Sclerenchyma and collenchyma are primarily for mechanical support and do not provide buoyancy.
