The correct option is A Hookworm
Hookworm females produce about 10,000-20,000 eggs per day in the small intestine of an infected person which then pass to the soil through feces. In the soil, they incubate and the immature larva is hatched out from the egg. Once they get mature develops hook-like structure. If exposed to human skin they attached with the skin through hook and penetrates into the blood.
