Multiple colliders on a prefab: how to know which one was hit?

I’m building a simple 2D games in C#.

One of my prefabs has 4 edge colliders (top, left, right, down). How can I know which one was hit in the OnTriggerEnter2D function?

Thanks!

Dont add the colliders onto one gameobject add multiple empty gameobject and add the colliders their and like reddevil said add scripts to those and check if they have been hit
