Which of the following could be found on either public or private land?
Reptile [31]
<span>The option that could be found on either public or private land is C. mine. A state park can only be found on public land, because parks are owned by states, not regular people. A single-family residence is only found on private land, because that is a house that a family owns. A factory is on private land only, because it belongs to a person or another company. Which leaves us with mines, that can be found both on private and public lands.</span>
