Getting a C after admitted into UCLA

I got accepted into UCLA for computer science major. The problem is that I am getting a C grade in one of my strongly recommended classes, and UCLA said that I have to let them know if I am getting a C, so they reconsider my admission. Can they reject me after I got admitted? If they do, I will have no schools to go to, so what should I do now? I appreciate any advice in advance.

same situation from CCSF, getting a C in engineering 38 class

If you don’t comply with the terms of your provisional admission, they certainly can rescind it. Each case is individually evaluated and, my guess is, if you are proactive,and transparent with them, and maintained a GPA north of 3, they will probably still let you in.
good luck.
