Which of the following does not apply to the concerted model for subunit behavior:
A) Each subunit can exist in a relaxed (R) and taut (T) conformation.
B) All subunits will be in either the R or the T conformation at the same time.
C) Some subunits can be in the R state while others are in the T state.
D) The presence of inhibitors will lead to more of the enzyme being in the T form
E) the presence of activators will lead to more of the enzyme being in the R form

The concerted model (also known as the MWC model) posits that all subunits of an enzyme change conformation simultaneously and thus cannot exist in mixed states (some in R and others in T) at the same time.
