Unity: How to remove inactive gameObject from List

Question

I made a List of gameObjects that are currently in my box collider and it works. However, when I set a gameobject inactive,

gameObject.SetActive(false); // To Eliminate Enemy

the gameObject remains in the List without being removed. How do I remove the gameObject from a List in the OnTriggerEnter function from another class?

PlayerLifeClass:

     private List<GameObject> ObjectsInRange = new List<GameObject>();
        public void OnTriggerEnter(Collider collider)
        {
            if (collider.tag != "Player" && collider.tag == "Zombie")
            {
                ObjectsInRange.Add(collider.gameObject);
                damage = ObjectsInRange.Count; //amount of zombies inside collider
               //***Over here***

                zombie.DamagePlayer(damage);
                Debug.Log(damage);
            }
        }
        public void OnTriggerExit(Collider collider)
        {
            if (collider.tag != "Player" && collider.tag == "Zombie")
            {
                //Probably you'll have to calculate which object it is
                ObjectsInRange.Remove(collider.gameObject);
                Debug.Log(ObjectsInRange);
            }
        }

ZombieClass:

    public class Zombie : MonoBehaviour
    {
        public int currentHealth;
        private Player player;
        private PlayerLifeCollider playerCollider;
    
        public void Damage(int damageAmount)
        {
            //subtract damage amount when Damage function is called
            currentHealth -= damageAmount;
    
            //Check if health has fallen below zero
            if (currentHealth <= 0)
            {
                //if health has fallen below zero, deactivate it 
                gameObject.SetActive(false); //***Over here***
     
            }

   public void DamagePlayer(int damage)
    {
         player.Life(damage);
      }
   }

If I understood what you want, Something like this would do,

PlayerLife Class

public static List<GameObject> ObjectsInRange = new List<GameObject>();

Zombie Class

public void Damage(int damageAmount)
    {
        //subtract damage amount when Damage function is called
        currentHealth -= damageAmount;

        //Check if health has fallen below zero
        if (currentHealth <= 0)
        {
            //if health has fallen below zero, deactivate it
            PlayerLife.ObjectsInRange.Remove(gameObject); 
            gameObject.SetActive(false); //***Over here***
            //You can also do a Destroy(gameObject) if you'd like;

        }
    }
