Example: I have an item that has two options (variants). I want to "force" the customer to pick one of the two variants. However, currently it defaults to the first variant. My concern is that the customer just clicks add to cart on the default when the actually need the second variant.
I tried creating a blank variant but they could just add that one to the cart....

Which theme are you using? Some themes have this option already built-in while others can have this added with some coding changes.
We actually have a tutorial available here to help you requires customers to select an option to add to cart. Check that out and let us know if you need any more guidance to get this done!
