Explanation / Answer

1) (b) Possess ostaria that unite auris interna and the air bladder, augmenting audition and (d) Liberate pheromones upon cutaneous injury - The Ostariophysi order consists of weberian apparatus, that helps in transmitting vibrations to the inner ear. Upon injury, these fishes release alarm substance (pheromones) that evokes a fright reaction from similar fishes that can recognize the pheromone.
