Text Solution

Verified by Experts

The correct Answer is:
D
Arthropods have a much reduced coelomic cavity . The space between the gut and body wall is mostly occupied by muscles and organs with blood containing interspaces . These spaces together form the haemocoel , which is not a true coelom as it is not lined by the mesodermal epithelium . however , greatly reduced true coelom exists in the form of a number of separate spaces , such as enclosing excretory and genital organs.
