What causes these dark rings to form in lawn grass?
a) This is where the garden fairies gather late at night to dance and sing and make merry while drinking tiny bellflowers full of odd potions and elixirs. The odd potions and elixirs slosh out of the flowers and over-fertilize the lawn in those places
b) This is where the spaceships carrying hoards of hungry rabbits land in the lawn. The rabbits are released out into the garden where they can hop around and gather food to take back with them on their return flight to their own planet.

And if you chose C you have to be laughing right now because that was a very funny scene in that movie. I laughed for days thinking about that scene.

And by the way there are several fairy rings in my back yard. As noted in this PDF from Purdue University, for the most part homeowners should just try to coexist peacefully with their fairy rings.
And that’s exactly what I plan to do, along with making up other
