How do I disable or Destroy Virtual Buttons using C#?

I've created a project and I want to be able to destroy the button after use. How do I go about it?

This is my code sample:

 public class AnswerOne: MonoBehaviour, IVirtualButtonEventHandler {
     
     
     void Start () {
         VirtualButtonBehaviour[] vbs = transform.GetComponentsInChildren<VirtualButtonBehaviour> ();
 
         for (int i=0; i < vbs.Length; ++i) {
             vbs[i].RegisterEventHandler(this);
         }
 
     }
 
 
     public void OnButtonPressed(VirtualButtonAbstractBehaviour vb){
 
             if (vb.name == "1Q1") {
                 new WaitForSeconds(2);
                 carlight.SetActive(true);    
             
             }
             
 
             
     }
 
     public void OnButtonReleased(VirtualButtonAbstractBehaviour vb){
         
         
         
         if (vb.name == "1Q1") {
             print ("1A1released");
                    //Destroy Code here
 
         }
         
         
     }
     
 }
