The correct option is A

Salmonella typhi

Typhoid is a water-borne disease caused by Salmonella Typhi. Typhoid fever can be prevented and can usually be treated with antibiotics. You can get typhoid fever if you eat food or drink beverages that have been handled by a person who is shedding Salmonella Typhi or if sewage contaminated with Salmonella Typhi bacteria gets into the water you use for drinking or washing food.
