I'm showing the last post of a blog on an external website that I'm developing out of wordpress.

<?php
    //Include WordPress
    define('WP_USE_THEMES', false);
    require('./blog/wp-load.php');
    //Define quantos posts serão exibidos
    query_posts('showposts=3');
?>
<?php while (have_posts()): the_post(); ?>
<li>
    <h4><?php the_title(); ?></h4>                      
    <span><?php the_time("d/m/Y"); ?></span>
    <?php the_category_ID(); ?>
    <?php the_content(); ?>
    <div>
    <a href="<?php the_permalink(); ?>">&laquo; Leia Mais...</a>
    </div>
</li>
<?php endwhile;?>

The point is that the blog is separated into two categories and I would like to display only one of them.

link where I got these functions.

Since WordPress version 4.7 no longer needs to load WordPress in this way to fetch content, just use the native REST API:

<?php
$curl = curl_init();

curl_setopt_array($curl, array(
    CURLOPT_RETURNTRANSFER => 1,
    CURLOPT_URL => 'http://example.com/wp-json/wp/v2/posts?per_page=3&categories={ID_DA_CATEGORIA}',
));

$resp = curl_exec($curl);
$posts = json_decode( $resp, true );
curl_close($curl);

foreach( $posts as $post ) : ?>
    <li>
        <h4><?php echo $post['title']['rendered']; ?></h4>
        <span><?php echo date("d/m/Y", strtotime( $post['date'] ) ); ?></span>
        <?php // {ID_DA_CATEGORIA} ?>
        <?php echo $post['content']['rendered']; ?>
        <div>
            <a href="<?php echo $post['link']; ?>">&laquo; Leia Mais...</a>
        </div>
    </li>
<?php endforeach;?>

Now $posts is an associative array with information from the last 3 posts in the category you requested. In this array are all the information that is being requested there in the markup as title, link, date, etc.

Example returned object:

{
    "id": 173,
    "date": "2017-07-25T01:35:08",
    "date_gmt": "2017-07-25T01:35:08",

        "rendered": "http://example.com//?p=173"
