What .php file ?

I am getting the following category tag in my post… and I want to remove it.

<header class="entry-header">
				<div class="entry-meta">
			<span class="cat-links"><a href="https://www.bernhardrieder.com/business/" rel="category tag">Business</a></span>
		</div>
		<h1 class="entry-title">Online Geld verdienen – Anf?nger macht 1400% Rendite</h1>
		<div class="entry-meta">
			<span class="entry-date">

I want to delete the a href link that points to my category business.
You see the URL link.

I can’t figure out what .php file this is coded.
I don’t want to use any CSS Edit.. I want to go into the specific .php file and delete that line.

thx for any little help,
appreciate it !
