Why Does a Patient with CO Poisoning Have Cherry Red

Why does a patient with CO poisoning have cherry red skin coloring instead of cyanosis?

A) CO poisons the hemoglobin and chemical alters the erythrocyte making it incapable of carrying oxygen. The red color is due to compensatory polycythemia which occurs immediately.
B) CO causes the hemoglobin molecule to break apart. The red coloration is from the hemoglobin fragments under the skin
C) Patients with CO poisoning hyperventilate so the red coloration is due to the increased WOB
D) CO rapidly fills sites on the hemoglobin where oxygen normally attaches. The high level of carboxyhemoglobin and saturated hemoglobin results in the red coloration
