• B. Contaminated water and food
• C. Improperly cooked measly pork
• D. From air through inhalation

Answer 1

The correct option is B Contaminated water and food

Ascaris lumbricoides parasitic worm causes ascariasis. 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. The larvae then pass through the stomach for a second time into the intestine, where they become adult worms.

So, the correct answer is 'Contaminated water and food'.
