Answer:
d.
Step-by-step explanation:
The rendering is always a browser job, so al answers where it is suggested that the web server does that are wrong.
Static web pages are actually pre-created HTML files on the web server file system. So all that has to happen is that the web server reads them from the file system and sends them back to the browser.
Dynamic web pages (e.g., PHP pages) first have to be run to generate HTML. That is the difference between answer c and d.
