Based on your file path, you are looking at very old version of AbanteCart (prior to 1.2).
Anyways, the solution might be similar:
<?php if ($options) { ?>
<?php foreach ($options as $option) { ?>
<div class="form-group">
<?php if (!in_array($option['html']->type, array('hidden'))) { ?>
<label class="control-label"><?php echo $option['name']; ?></label>
<?php } ?>
<div class="input-group col-sm-10">
<?php echo $option['html']; ?>
</div>
</div>
<?php } ?>
<?php } ?>
$option['html'] shows element ready HTML in echo, but it is actually an object of HtmlElementFactory.
You can use methods in the object to get option details and build your own custom HTML for your element.
Ultimately, you can edit HTML template for given HTML element located in folder /storefront/view/default/template/form/*
Look into core/engine/html.php
