The OPUS processing service uses a web address on which NOAA domain?

OPUS is a web-based processing service provided by the National Geodetic Survey of NOAA, so it lives on the NGS portion of NOAA’s website. That service is accessed through the OPUS directory under the NGS domain, which is www.ngs.noaa.gov/OPUS/. This is the designated entry point for uploading GNSS data, running the processing, and retrieving results. Other options point to different parts of the site or to the general NOAA domain, or to a static data area, and they do not host the OPUS processing interface. Hence this URL is the correct one.
