WooCommerce Extra Product Options - php

Question

Any one please help me find the solution to the following:
I want to show specific product option value on woocommerce email template.
The code to show all option value:
public function tm_woocommerce_email_after_row($item_id, $item, $order , $flat=false){
$html = '';
$has_epo = isset($item['item_meta']) && isset($item['item_meta']['_tmcartepo_data']) && isset($item['item_meta']['_tmcartepo_data'][0]);
if ($has_epo){
$epos = maybe_unserialize($item['item_meta']['_tmcartepo_data'][0]);
$current_product_id=$item['product_id'];
$original_product_id = floatval(TM_EPO_WPML()->get_original_id( $current_product_id,'product' ));
if (TM_EPO_WPML()->get_lang()==TM_EPO_WPML()->get_default_lang() && $original_product_id!=$current_product_id){
$current_product_id = $original_product_id;
}
$wpml_translation_by_id=$this->get_wpml_translation_by_id( $current_product_id );
foreach ($epos as $key => $epo) {
if ($epo){
if(!isset($epo['quantity'])){
$epo['quantity'] = 1;
}
if(isset($wpml_translation_by_id[$epo['section']])){
$epo['name'] = $wpml_translation_by_id[$epo['section']];
}
if(!empty($epo['multiple']) && !empty($epo['key'])){
$pos = strrpos($epo['key'], '_');
if($pos!==false) {
$av=array_values( $wpml_translation_by_id["options_".$epo['section']] );
if (isset($av[substr($epo['key'], $pos+1)])){
$epo['value'] = $av[substr($epo['key'], $pos+1)];
}
}
}
if ($flat){
$html .= "\n" . $epo['name'] . ' : ' . $epo['value'];
$html .= "\n" . sprintf( __( 'Quantity: %s', 'woocommerce' ), ( $epo['quantity'] * (float) $item['item_meta']['_qty'][0] ) );
if (!empty($item['item_meta']['tm_has_dpd'])){
}else{
$html .= "\n" . sprintf( __( 'Cost: %s', 'woocommerce' ), (wc_price( (float) $epo['quantity'] * (float) $epo['price'] * (float) $item['item_meta']['_qty'][0] )) );
}
}else{
$html .= '';
$html .= ''.$epo['name'].': '.$epo['value'].'<br/>';
$html .= '';
}
}
}
}
echo $html;
}
