I am just a beginner and have written a very simple basic plugin structure.

What’s the mistake that’s causing the “Treehouse Badges” menu name not to appear under the Settings menu in the admin section of WordPress.

The only issue was that the capability was specified incorrectly when using add_options_page(). The capability should be manage_options. Note the underscore, no space:

function basic_treehouse_badges_menu() {
  /*
     *  Use the add_options_page function
     *  add_options_page( $page_title, $menu_title, $capability, $menu-slug, $function )
     *
    */
  add_options_page(
    'Official Tree House Badges Plugin',
    'Treehouse Badges',
    'manage_options',
    'wp-treehouse-badges',
    'wptreehouse_badges_option_page'
  );
}
add_action('admin_menu','basic_treehouse_badges_menu');

function wptreehouse_badges_option_page() {
  if( !current_user_can ('manage_options')) {
    wp_die('You do not have sufficient permission to acces this page.');
  }
  echo '<p> welcome to our plugin page </p>';
}
