Planaria is generally eating the dead animals with the help of muscular sucker which work as mouth. Here is first option is correct.
Other facts that it does not contain proboscis and protnephridia are the part of excretory system. It does not show phagocytosis because it is higher form of animal kingdom not like amoeba or paramecium. It is living on dead marterial unlike arthropods it does not wrap the prey.
Trichinella stays in nurse cells. In parasitology nurse cells termed used for those cells which nourish the parasite. Here trichinell release in the circulation than it finds skeletal muscle cells where hypoxic conditions help in their development.
