Solution
The correct option is B Nasal cavity
Seabirds have their own desalinization systems to deal with excess salt taken in by drinking seawater and feeding in the ocean, in the form of glands that lie in shallow depressions in or above the eye sockets. Salt glands in birds are also called as supraorbital or nasal glands. For most seabirds, the excess salt excreted from the blood by these glands passes as a concentrated solution through ducts into the nasal cavity and is eliminated in liquid form through the nostrils, often accompanied by vigorous shaking of the bird's head or forced "sneezing."
