[2025-10-02T06:16:45.032963] [PI reasoning] **Determining vitamin deficiency**

I need to answer an exam-style question about a patient with specific symptoms like fissured red tongue and angular stomatitis, along with decreased RBC glutathione reductase activity. The evidence points to riboflavin deficiency since that's linked to low RBC glutathione reductase. While B6 and B12 deficiencies cause peripheral neuropathy, they don't lower this enzyme. Therefore, the best option is A, indicating riboflavin deficiency. I’ll search for a supporting article for citation.
