A 7-year-old girl developed an erythematous malar rash with perioral pallor that has now spread to the extremities and evolved into a macular to morbilliform, lacy, reticular rash. The rash was preceded by headache, runny nose, low-grade fever, and sore throat. Her serum is positive for immunoglobulin M (IgM) antibodies against a small DNA virus. What is the most likely diagnosis?

A. Measles
B. Varicella
C. Rubella
D. Erythema infectiosum
