Solution
The correct option is D Intestine
- Larvae hatch from the eggs in your small intestine(first moult) and then penetrate the intestinal wall to travel to your lungs via your bloodstream or lymphatic system. After maturing for about a week in your lungs, the larvae break into your airway and travel up your throat, where they're coughed up and swallowed.
- Maturation. Once back in the intestines, the parasites grow into male or female worms (last moult). Female worms can be more than 15 inches (40 centimeters) long and a little less than a quarter inch (6 millimeters) in diameter. Male worms are generally smaller.
So, the correct answer is 'Intestine'.
