Enfold – Post info links, only linking deepest category

Under the post titles you usually get
Date / in Category 1, Category under 1, Category under the one under 1/ By person who made the post

If I have
Category one
–Category two
—-Category three

How can I modify the template so that it does not list all the categories but ONLY the deepest one which in this example would be
Date / in Category three / By person who made the post

This is because I do not want to show all the categories above the one we are in as links as I would rather have people navigate via the navigation instead of clicking those posts breadcrumbs. I guess it has to be in here within the template

$taxonomies  = get_object_taxonomies(get_post_type($the_id));
                    $cats = '';
                    $excluded_taxonomies =  apply_filters('avf_exclude_taxonomies', array('post_tag','post_format'), get_post_type($the_id), $the_id);

                    if(!empty($taxonomies))
                    {
                        foreach($taxonomies as $taxonomy)
                        {
                            if(!in_array($taxonomy, $excluded_taxonomies))
                            {
                                $cats .= get_the_term_list($the_id, $taxonomy, '', ', ','').' ';
                            }
                        }
                    }

                    if(!empty($cats))
                    {
                        echo '<span class="blog-categories minor-meta">'.__('in','avia_framework')." ";
                        echo $cats;
                        echo '</span><span class="text-sep text-sep-cat">/</span>';
                    }
