How to set isTrigger to false of two colliders in 1 game object

hi, I created one game object with two box colliders(A and B). both these colliders are set isTrigger to true in the inspector and I would like to set these two colliders (isTrigger) into false when the player enter a different collider (C). however only one collider(A) is set to isTrigger into false when i run the below code. can anyone please tell how can i set both colliders(A and B) to false. Thank you.

bool Ans = false;
public GameObject Fig ;
public GameObject figCol;
public BoxCollider ansCol;

	public AudioClip endGame;
	public AudioClip StartAns;
	
	
	
	
	void OnTriggerEnter( Collider col)
	{  
		if (Ans == false && col.gameObject.tag == "Player")

	{		ansCol.isTrigger = false;
			
			audio.clip = StartAns;
			audio.Play ();
			StartCoroutine ("AudioStart");

		}	// end if	

	}//end function on trigger enter

you need to google unity compound colliders.

if you want to use two on a single game object they can’t be the same type of primitive.

Using a box and a sphere works, but not two boxes.

if you use a box and a sphere you can reference them seperately through get component

getcomponent<BoxCollider>()

getcomponent<SphereCollider>()

That wouldn’t really work,
The trigger that is referenced will always return the first one in the inspector.

The better approach is to add 2 empty children GameObjects.
Attach a collider to each.

And test for both children in the OnTriggerEnter for each collider.
If you want more control, attach scripts to each child and access it using.

col.gameObject.GetComponent().doWhatever();
