Add objects to list automatically

I'm building a board game with quizzes. The problem is: now I have 2 Quiz cameras for testing. After the player gets one of them right, it switches back to the MainCamera, ok. But after it gets the answer only the camera gets destroyed. How do I destroy the random camera it picked + the rest of the quiz?
I think the way is creating a list of objects that will be destroyed... but how??

Code (CSharp):

1. {
2.  
3.     public void ButtonReturnToMainCamera()
4.     {
5.         if (m_canSwitchBack)
6.         {   // Swap back.
7.             m_camMain.enabled = true;
8.             m_camTemp.enabled = false;
9.             m_canSwitchBack = false;
10.             Destroy(m_camTemp.gameObject);
11.         }
12.     }
13.     void Start()
14.     {
15.         m_camMain = Camera.main;
16.         foreach (var cam in camerasList)
17.             cam.enabled = false;
18.     }
19.     void OnTriggerEnter2D(Collider2D collision)
20.     {
21.         if (collision.CompareTag(m_player)
22.             && m_triggered == null)
23.         {
24.             m_triggered = StartCoroutine(EnableRandom());
25.         }
26.     }
27.     IEnumerator EnableRandom()
28.     {
29.         yield return new WaitForSeconds(2f);
30.         if (camerasList.Count != 0)
31.         {
32.             // Let's pick our random camera.
33.             var randomInt = Random.Range(0, camerasList.Count);
34.             m_camTemp = camerasList[randomInt];
35.             camerasList.RemoveAt(randomInt);
36.             // Swap over.
37.             m_camMain.enabled = false;
38.             m_camTemp.enabled = true;
39.             m_canSwitchBack = true;
40.             m_triggered = null;
41.             // Create list and destroy the quiz      
42.          
43.         }
44.     }
45.     const string m_player = "Player";
46.     [SerializeField] List<Camera> camerasList;
47.     Camera m_camMain;
48.     Camera m_camTemp;
49.     Coroutine m_triggered;
50.     bool m_canSwitchBack;
51. }

 

You waited all of three minutes after your last post in your previous thread before making a new thread to ask the same question?

I thought that now the plan it's different, I might be calling the wrong people with the title
