B1/B2 visa status from administrative processing to Refusal

I had an interview on 03-02-2022 for B1/B2. The interview went very well and the officer kept my passport.
Yesterday, the status of my visa was under administrative processing today, I checked it Refused.

how this could be possible? i was told once they keep your passport for sure you will get the visa.

how they can refuse my visa after keeping the passport.

please let me know if anyone has anything regarding this matter.

Scroll down the article, it explains why you see refused status.
