[2025-09-30T21:49:50.281866] [PI reasoning] **Answering the quiz on thalassemia**

I need to address the quiz question about alpha thalassemia, noting that it refers to decreased production of alpha chains, which leads to an excess of beta chains. Therefore, option C, which states "Excess beta chain," is correct. This happens because the unpaired beta chains accumulate when alpha chains are deficient. For added accuracy, I might quickly look up a reliable source to provide a citation if necessary.
