Solution
The correct option is B Gills
Gills are the special organs present in many aquatic animals where gas exchange occurs. Fishes do have nostrils, they actually lead into organs of smell which are very sensitive, so that a fish can detect the presence of food in the water. Their nostrils don't play any role in the breathing process.
