[2025-10-01T19:20:56.036425] [PI reasoning] **Evaluating infant nutrition statements**

Option C claims that cow's milk contains more potassium (K+) and sodium (Na+) than infant formula, which is supported by studies showing higher levels in cow's milk. Therefore, the false statement must be A. I can cite two sources for this reasoning: Montalto et al. 1985 provides evidence regarding electrolyte differences, and Pepe 2013 offers details on protein composition. Thus, the final answer is A, because cow's milk has a different nutrient profile compared to formula.
