How does the system decide which item is free if a customer has multiple eligible products in their cart?

I'm running a Buy One Get One (BOGO) promotion in my online store and want to understand exactly how the system determines which product becomes the free item when a customer has multiple eligible products in their cart. This is crucial for ensuring fair and predictable promotions that don't create customer confusion or unexpected pricing scenarios. I need clarity on the selection logic to set up my promotion rules correctly and communicate them transparently to my customers.
