The correct answer is:

a. Eukaryotic RNA polymerases require transcription factors for initiation, while prokaryotic RNA polymerases do not.

In eukaryotes, RNA polymerase requires the assistance of transcription factors to recognize and bind to specific DNA sequences known as promoters, which initiate transcription. These transcription factors help in the assembly of the RNA polymerase complex and ensure proper initiation of transcription. In prokaryotes, however, RNA polymerase can directly recognize and initiate transcription at the promoter sequences without the need for transcription factors.
