Correct answer.

Incidentally, but not at all coincidentally, this is precisely why Target stores always have those red concrete spheres in front of the doors. Which are typically nearly exactly the same height and thus have the same potential amount of visibility/invisibility below a driver's sightline as this rock. It's to prevent morons from crashing their vehicles through the doors.

The rock(s) pictured are not even in the parking lot like this Wal Mart pole. If you leave the road, it is reasonable to expect that you will encounter obstacles.
