Solution

The correct option is D Chemoreceptor
The osphradium is a chemoreceptive sense organ that monitors the water currents entering the mantle cavity. It has a patch of sensory epithelium on the gill membranes which acts as chemoreceptors to determine the amount of sediment in the water being taken inside.
