Echo array terms - php

Question

I'm looking to echo part of an array, what is the best method of echo'ing part of an array into a data field
I have an array that has the terms => subscription and need to pull that field into my input data-subscription="[echo subscription in here ]"
$quantites_required = false;
$previous_post = $post;
$count = 0;
$tax_query_args = [
'post_type' => 'product',
'tax_query' => [
[
'taxonomy' => 'product_type',
'field' => 'name',
'terms' => 'subscription',
],
],
];
$tax_query = get_posts($tax_query_args);
global $grouped_product;
foreach ($tax_query as $post) {
global $post;
$price = get_post_meta(get_the_ID(), '_price', true);
?>
<li id="product-<?php the_ID();?>" <?php post_class();?>>
<div class="prod-name">
<div class="radio">
<input type="checkbox" id="product-<?php the_ID();?>" value="1" name="quantity[<?php the_ID();?>]" class="wc-grouped-product-add-to-cart-checkbox js-group-item-sel" <?php echo ($count != 0 ? '' : ' checked="checked"'); ?> data-subscription="[echo terms subrciptions here]" />
<label for="product-<?php the_ID();?>">
<?php echo the_title(); ?>
</label>
</div>
</div>
<div class="prod-price" data-price="<?php echo number_format($price, 2); ?>">
<p>
<?php echo wc_price($price); ?>
</p>
</div>
<div class="prod_flag">
<?php get_product_flags(true); //Hide featured for grouped child items. ?>
</div>
<?php
$count = $count + 1;
}
$count = 0;

Replace this line
<input type="checkbox" id="product-<?php the_ID();?>" value="1" name="quantity[<?php the_ID();?>]" class="wc-grouped-product-add-to-cart-checkbox js-group-item-sel" <?php echo ($count != 0 ? '' : ' checked="checked"'); ?> data-subscription="[echo terms subrciptions here]" />
with
<input type="checkbox" id="product-<?php the_ID();?>" value="1" name="quantity[<?php the_ID();?>]" class="wc-grouped-product-add-to-cart-checkbox js-group-item-sel" <?php echo ($count != 0 ? '' : ' checked="checked"'); ?> data-subscription="<?php echo ($tax_query_args['tax_query'][0]['terms']); ?>" />
