How to display an array

Hello, i have problem with displaying typography options.

here is what i doing (functions.php:

function themebg(){ ?>

     <style type="text/css">
         header#head_page .desktop li a {<?php ot_get_option( 'menu' ); ?>}

     </style>
 <?php
 } add_action('wp_head', 'themebg');

This code create empty css, i assume this is an array, but i dont know how to display it properly.
