Solution

The correct option is B Ascaris
Man acquires the infection by directly ingesting Ascaris eggs through contaminated food or water. The second larva of Ascaris hatches out of the egg in the small intestine and penetrates the intestinal wall to enter the blood stream.
Thus, the correct answer is option A.
