Solution
The correct option is A Ascon type
There are different types of canal systems in sponges which are as follows-
Ascon type - It is the simplest type of canal system. Flagellated spongocoel are present here.
Sycon type - It is a more complex system as it is folded version of the asconoid body. It has flagellated radial canals.
Leucon type - This type of canal system is formed from the rhagon type by the out folding of the choanocyte layer. In this type, oval or rounded chambers lined by flagellated cells are formed by evagination of the radial canals.
Rhagon type - This type of canal system is found in the larva of Demospongiae, called as rhagon, which has a broad base and is conical in shape.
Leucosolenia has ascon type of canal system.
Hence the correct option is A.
