A 67 year-old male presents with hemoptysis and cough for the past 3 months. He also has night sweats but no weight loss. He is afebrile with an unremarkable physical exam. His chest X-ray shows three cavitary lesions all in the upper left lung lobe. His treatment regimen consists of isoniazid, rifampin, pyrazinamide and ethambutol. After several months of treatment his pulmonary symptoms have decreased but the patient states he has new tingling sensations in his hands and feet. He does not have diabetes mellitus. At this point you realize that you forgot to supplement his drug regimen with which of the following?

A. Iron (ferrous sulfate) because rifampin can cause pernicious anemia
B. Vitamin B6 because isoniazid decreases its absoprtion
C. Vitamin B12 because isoniazid decreases its production
D. Vitamin D because isoniazid may decrease its production in the kidney
E. Folate because rifampin may inhibit its absorption
