[2025-10-02T02:52:49.511637] [PI reasoning] **Identifying alkali disease causes**

I need to clarify the element responsible for causing blind staggers and alkali disease in livestock. It looks like these conditions are linked to chronic selenium intoxication, so I'm leaning towards selenium as the answer. To back this up, a quick search should help gather more evidence about "alkali disease" in cattle due to selenium toxicity. Therefore, my answer is definitely Option C: Selenium. Let's find the references to support this!
