Actually none of the answers satisfies me...
Parasites are organisms which live at the expense of others, without giving anything in return. Parasitic is NOT THE ONLY TYPE OF RELATIONSHIP that can exists between two organisms, in which one lives inside the other.
Symbiosis, for example.
And for that matter, viruses and bacteria may also live inside pluricellular hosts.
But if you have to chose one, chose "parasite".

The answer is C-PARASITE... know why?
Because there exist different relationship between or among animals in an ecosystem...
1. mutualism- both organism benefit on one another and neither is harmed
2. commensalism- one organism benefits from the other while the other neither benefits nor harmed
3. competition- animals fight for food, territory and life
4. predation- one acts as food (prey) while the other acts as the eater (predator)
...Lastly
5. PARASITISM- one organism benefits from the other while the other (host) is harmed. There are 2 types of parasitism...
5.1 endo parasites- parasites w/c are found outside the body of the host (ticks, louse and etc)
5.2 ecto parasites- parasites w/c are found inside the body of the host (bacteria, amoeba and etc)
Sorry for not making much help... That s all I can give you...
