Hint: Aerenchyma is a spongy tissue that forms spaces or air channels in the leaves, stems and roots of some plants, which allows some plants, which allows exchange of gases between the shoot and the root.
Complete answer:
Arenchyma is majorly found in aquatic and wetland plants. Arenchyma is a modified parenchyma, where the cells are arranged with regular air chambers in between to facilitate diffusion of gases in and out. They also provide buoyancy to hydrophytes like lotus and water hyacinth that help them float on water.
Aerenchyma is the term given to plant tissues containing enlarged gas spaces exceeding those commonly found as intracellular space. It is formed in the roots and shoots of wetland species and in the same dryland species in adverse conditions, either constituently or because of abiotic stress.
Aerenchyma is a tissue compared to a network of interconnected gas conductivity intercellular spaces which provide plant roots with oxygen under hypoxic conditions.
Therefore, from the above explanation the correct option is (C) Hydrophytes.
Note: A type of tissue called aerenchyma which contains air spaces produced by separation, tearing, or dissolution of the cortex cell walls. Cortical cells in herbaceous stems, young woody stems, and stems of succulents (cacti and other fleshy plants) contain chloroplasts and can therefore convert carbon dioxide and water to simple.
