Is there a Application. that closes both a picture and text in C#?

Question

I am writing a program in Unity for my main menu. I got the Quit button, it just takes

public void ExitGame()
    {

        Application.Quit();

    }

But I need something that only exits the window not the game. Is it Application.Quit and I'm just paranoid? Or is something that I don't know of. Please help!

Edit: Would

 public void ExitOptions()
    {
        optionMenu.enabled = false
    }

work? Edit 2: I'm suposed to add code here: I will make a short cleaner version after I'm done writing it

using UnityEngine;
using UnityEngine.UI;
using System.Collections;

public class menuScript : MonoBehaviour {

    public Canvas quitMenu;
    public Button startText;
    public Button exitText;
    public Canvas optionMenu;
    public Button WASDText;
    public Button arrowText;
    // Use this for initialization
    void Start ()

    {
        quitMenu = quitMenu.GetComponent<Canvas>();
        startText = startText.GetComponent<Button>();
        exitText = exitText.GetComponent<Button>();
        quitMenu.enabled = false;
        optionMenu = optionMenu.GetComponent<Canvas>();
        WASDText = WASDText.GetComponent<Button>();
        arrowText = arrowText.GetComponent<Button>();


    }


    public void ExitPress()
    {
        quitMenu.enabled = true;
        startText.enabled = false;
        exitText.enabled = false;
    }

    public void OptionPress()
    {
        optionMenu.enabled = true;
        WASDText.enabled = true;
        arrowText.enabled = false;
    }

    public void NoPress()
    {
        optionMenu.enabled = false;
        startText.enabled = true;
        exitText.enabled = true;

    }

    public void WASDPress()
    {
        optionMenu.enabled = true;
        WASDText.enabled = true;
        arrowText.enabled = false;
    }

    public void ArroPress()
    {
        optionMenu.enabled = true
        WASDText.enabled = false
        arrowText.enabled = true
    }
    public void StartLevel()
    {
        Application.LoadLevel (1);

    }

    public void ExitGame()
    {
        Application.Quit();

    }

    public void ExitOptions()
    {
        optionMenu.enabled = false
    }
}

If Text component is nested in Image component, justs call:

optionMenu.SetActive(false);

It will make it inactive along with all of its children.

If you are closing it from another Unity3D UI element, you can attach EventTrigger or if it is a Button , you can drag and drop Image to it's OnClick() event and leave checkbox unchecked (in example below it will enable object of name "Canvas2" beacause checkbox is checked):
