Can someone me plz which of these is a characteristic of a parasite? it is a organism. it lives inside or on a host. it makes its own food. it is always visible to the naked eye.

The correct answer is it lives inside or on a host.

A is incorrect because a parasite steals from the host, without giving anything in return. Much like a leech

C is incorrect because leeches almost always use their host as a food source

D is incorrect because parasites can often dig beneath the host's skin to be hidden from sight

Ihaven't done that yet, so no idea,but this is not the right place to ask
