[2025-09-29T13:29:07.144948] [PI reasoning] **Determining Streptococci's Role**

I need to address how streptococci adhere to tooth surfaces, contributing to caries. The options include their resistance to penicillin, acid production during metabolism, extracellular polysaccharides, or carbohydrate fermentation. Streptococcus mutans is significant in dental caries, primarily adhering through extracellular polysaccharides (glucans) formed from sucrose. While they produce acid, the adherence is specifically thanks to these polysaccharides. So, the answer is C. I’ll look for citations about S. mutans and their adherence properties.
