Hide 'Screen Option' tab from your wordpress dashboard with some coding !!!

Hope all of you are very fine. when we visit our wordpress dashboard then we see a tab menu on lef side corner which is named 'Screen Option' like this:

In this menu we not need more important work so if you want you can hide it from your wordpress sites dashboard. for this work you need copy this code:

function remove_screen_options_tab()
{
    return false;
}
add_filter('screen_options_show_screen', 'remove_screen_options_tab');

After copy that code go to your wordpress dashboard and select edit of yur current theme now open 'functions.php' file with edit mode and paste here. after paste save it. now refresh your wordpress dashboard now you can see that 'Screen Option' tab is hidden.
