Random code under my comments box

If you go to my blog https://www.thelawsoffashion.com and click on any post and scroll down to the comments section, there is random code beneath the comment box. I do not believe I would alter the theme code because I am not sophisticated at all in code.
I also do not think I would have installed some sort of widget to add the comment box, but I am not sure, I can’t find anything like that on my dashboard.
Any help would be very much appreciated. Thank you.
