How to hide a specific user role option in a user role list?

Question

I have to hide Administrator user role in the "User roles" area for these pages:

• /wp-admin/users.php
• /wp-admin/user-new.php
• /wp-admin/user-edit.php

I would like to hide this role option for other users that have an ability to select the Administrator role in order to prevent anyone other to give admin rights.

SOLUTION:

// Remove Administrator role from roles list
add_action( 'editable_roles' , 'hide_adminstrator_editable_roles' );
function hide_adminstrator_editable_roles( $roles ){
    if ( isset( $roles['administrator'] ) && !current_user_can('level_10') ){
        unset( $roles['administrator'] );
    }
    return $roles;
}
