What Does the Specific Protein Receptor Theory of the Action

What does the specific protein receptor theory of the action of local anesthetics suggest?

A) The specific protein receptor theory suggests that anesthetics that are highly lipid soluble cause the lipoprotein matrix of the nerve membrane to expand, narrowing the sodium channels, thus preventing depolarization.
B) The method by which the impulses travel down the length of the nerve affects whether nodes of Ranvier are stimulated or not.
C) Displaced Ca++ and local anesthetic drugs compete to bind to receptor sites within the ion channels of cell membranes.
D) All of the above
