Solution
The correct option is C Contaminated food and water
Ascariasis is a disease caused by the parasitic roundworm Ascaris lumbricoides. Ascariasis does not spread directly from person to person. Infection occurs by eating food or drink contaminated with Ascaris eggs from feces. The eggs hatch in the intestines, burrow through the gut wall, and migrate to the lungs via the blood. There they break into the alveoli and pass up the trachea, where they are coughed up and swallowed. The larvae then pass through the stomach for a second time into the intestine where they become adult worms.Therefore, the correct answer is option C.
