A 62-year-old female arrives for her annual physical. She complains of itching in her hands along with headaches and vertigo. A routine complete blood count (CBC) shows red blood cells (RBCs) of 8.2 million/μl, white blood cells (WBCs) 37,000/μl, and platelets 640,000/μl. Her erythropoietin levels are lower than normal. The primary diagnosis would be

A. The critical concentration (Cc) is the concentration at which G-actin monomers are in equilibrium with actin filaments.
B. At monomer concentrations below the Cc, no polymerization takes place. 
C. When polymerization is induced at monomer concentrations above the Cc, filaments assemble until steady state is reached and the monomer concentration falls to Cc.
D. At steady state, the concentration of monomeric actin below the critical concentration.
