Answer:

None of the answers is correct, because prokaryotic cell doesn't have nucleus

Explanation:

In eukaryotic cell, primary transcript is RNA synthesized via transcription in the nucleus. After processing it becomes mature mRNA. The processes of processining are addition of the 5' cap, 3'-polyadenylation, and alternative splicing (excision of introns). Because during the processing of RNA introns are removed the primary transcript is larger than the mRNA.
