B Correct answer
Explanation

The larvae liberated into the small intestine do not directly develop into mature worms. The rhabditiform larvae penetrate the gut mucosa and are carried by the portal circulation to the liver, where they live for 3 to 4 days. Finally, they pass out of the liver and enter the pulmonary circulation through the right heart. In the capillary of the lungs, they grow almost ten times bigger.
