Which of the following is true about the relationship between trigger colliders and physics interactions?

The statement regarding trigger colliders and their relationship with physics interactions is accurate in that trigger colliders do not result in physical interactions. Trigger colliders in Unity are specifically designed to detect when other colliders enter, exit, or stay within their bounds without physically affecting those colliders.

When a trigger collider is activated, it does not exert any physical forces or have mass; instead, it sends messages, often referred to as trigger events (like OnTriggerEnter, OnTriggerStay, and OnTriggerExit), which can be used to initiate game logic. This allows developers to implement various interactive mechanics without impacting the physics calculations that govern movements and collisions in the game world.

In contrast, normal colliders interact with the physics engine in a way that involves physical responses, like bouncing off each other, resulting in movement, or applying forces based on their interactions. Thus, the distinguishing feature of trigger colliders is their role in non-physical interactions, which makes the choice regarding their lack of physical interactions correct and highlights the different purposes of colliders in Unity.
