How Does Ascaris Lumbricoides, an Intestinal Parasite, Cause Choking and Pulmonary

How does Ascaris lumbricoides, an intestinal parasite, cause choking and pulmonary symptoms in some people?

A) People inadvertently inhale Ascaris worms when they bring contaminated food close to their mouths; these cause pulmonary blockages.
B) Ingested Ascaris larvae penetrate intestinal capillaries, from where they are carried to the lungs, causing coughing and shortness of breath. 
C) Ascaris larvae are highly allergenic; when they are ingested, they cause an allergic reaction which includes coughing.
D) Ascaris is a pulmonary parasite; it only enters the intestine of people with other lung conditions, including asthma.
E) Ascaris, being anaerobic, form large cysts in pulmonary tissue; these accumulate in the lungs, causing coughing.
