How to change "Reply" in comment section

Hi
I want to change the text "Reply" that appears in the comment section. May I know what the target file name is? I coundn't find it in functions.php or comments.php

Thank you

 

Go to comments.php present in your theme directory and replace the code given below with the code shown in image

Code:

  <?php wp_list_comments(array('reply_text'=>'Enter your text here'));
?>

Sending image for reference

 

It worked. Thank you.
