Answer: Mine
Explanation:
The options are:
a. state park
b. single-family residence
c. mine
d. factory
We should note that a state park tht is, a park that belongs to the government would be found in a public land since it belongs to the state.
Also, a single family residence would be found on a private land since it's not a government property. A factory would be found on a private land.
Therefore, the answer is mine as this can be found on either private or public land.
