$a \to$ regulator,$b \to$ conformer,$c \to$ partial regulator

(A) In the provided graph,the $x$-axis represents the external level and the $y$-axis represents the internal level of organisms.Line $a$ shows a constant internal level regardless of changes in the external level,which represents a regulator.Line $b$ shows that the internal level changes in direct proportion to the external level,which represents a conformer.Line $c$ shows that the organism can regulate its internal level only up to a certain point,after which it conforms to the external environment,representing a partial regulator.Therefore,$a$ is a regulator,$b$ is a conformer,and $c$ is a partial regulator.
