"Any" way?
You can grow them, and see which of the three autoflowers under 18 hour lighting. Note that you only have to grow two of the three here to get your definitive answer, and you might get it growing only one, IF that one is the autoflower.
That's probably the most RELIABLE way.
*IF* you're familiar with the seeds of the strain in question you *might* be able to tell one from the other just based on the size/color of the ceeds, or even if one just looks different than the other two. But clearly that doesn't apply here or you wouldn't be asking.
Lastly, you may be able to tell by leaf shape/plant structure, but again only if you're somewhat familiar with the lines in question.
