D. All of the above.
The worm shown in the picture above represents Taenia solium.
The pork tapeworm Taenia solium can cause two distinct forms of infection in humans: adult tapeworms in the intestine or larval forms in the tissues (cysticercosis).
Humans are the only definitive hosts for T. solium; pigs are the usual intermediate hosts, although other animals may harbor the larval forms.
Neurocysticercosis manifests an average of 5 years after exposure, but may cause symptoms in the first year of life.
