Contagious diseases are caused by pathogens that can easily spread between people through actions such as touching, sneezing, and coughing. Non-contagious diseases, as the name suggests, are not spread between people and are usually caused by factors such as genetics, lifestyle, or environmental factors. Systemic diseases affect the entire body, while allergies are specific immune reactions to a normally harmless substance. Therefore, the most appropriate answer for a disease that is spread through personal contact would be C contagious disease.
