Prefab Instance Problem

Unity Engine
1

Okay so i made a script that uses ray casting to tell if you clicked on a tree and if you click on a tree it falls, but the problem is i am using a prefab of a tree with this script on it, so when i click on 1 tree they all fall because they are all using the same script and are all just instances of the prefab, i was wondering what would be a solution to this.

Here is the script im using:

using UnityEngine;
using System.Collections;

public class treeFalling : MonoBehaviour {

    //Get the rigidbody
    public Rigidbody rb;
    //Get the raycast
    public Ray ray;
    public RaycastHit hit;

    // Use this for initialization
    void Start() {
        //Get components
        rb = GetComponent<Rigidbody>();
        //Tree rotation
        treeRotation();
    }

    // Update is called once per frame
    void Update() {
        treeRaycast();
    }

   
    public void treeRaycast() //Check if the player clicked the tree and if they did make it fall
    {
     ray = Camera.main.ScreenPointToRay(Input.mousePosition);

        if (Input.GetMouseButtonDown(0))
        {
            if (Physics.Raycast(ray, out hit, 100))
            {
                if (hit.transform.tag == "chopable")
                {
                    rb.isKinematic = false;
                }
            }
        }
    }

This error occurs because every tree is checking to see if a ‘choppable’ was hit. To fix it, add an additional conditional to check if the ‘choppable’ hit was a child or the root object that the script is attached to. You can get local heirarchy data from a reference to the Transform component.
