Gene expression control that occurred after the generation of RNA is (blank) ?

A:Controlled at transcription

B:Controlled before transcription

C:Controlled after transcription

D:Controlled after translation

After the generation of the RNA would indicate that

C. It is controlled after transcription

Now it could also be translation (because that is after the protein is made) - but because your question asks specifically after the RNA is formed (that process is called transcription) that would indicate that your answer is C.
