The correct answer is - the more specialized pharyngeal jaws are for one diet, the less adapted they are for the ingestion of other foods
Explanation:
Pharyngeal jaws are also called throat jaws and are specific for the prey. These jaws have strong muscles and plastic or easy-to-modify teeth. If an organism has pharyngeal jaws specialized for a specific diet or prey it will have lesser chances to adapted well according to the new diet. For instance, pharyngeal jaws highly specialized for scale eating will not be able to adapt well if the fish ingests algae.
