This is the only way of choice explained in a sutta. So mentioning this cannot be off topic.
The way the question was asked reflex a belief of intermediate state. I learned most people in the suttacentral community beleive that there is an intermediate state. I do not think there is even a single bit of possibility to believe likewise according to EBTs.
So I am not gong to dump my ideas here about intermediate state. Without an intermediate state a being cannot have a chance to selsect his family or where he is going to be reborn at all. Whole process of death and rebirth driven by kamma.
