Solution
The correct option is C Respiration
Pneumatophores are erect roots that are some form of upward appendage or extension of the underground root system. Because these roots are exposed at least part of the day and not submerged underwater, the root system can obtain oxygen in an otherwise anaerobic substrate. In Avicennia and Sonneratia species, the pneumatophores are erect side branches of the horizontal roots which grow just below the soil. So, pneumatophores take part in respiration and not in excretion, feeding and reproduction.
Thus, the correct answer is option C.
