C Correct answer
Explanation

Tooth decay (dental caries) affects nearly 3.5 billion people globally, making it the most widespread non-contagious disease. AIDS is infectious/contagious, while fever is merely a symptom rather than a specific disease. Cancer, though non-contagious, has significantly lower prevalence compared to tooth decay.
