The correct answer is: C) mRNA
Since the process of transcription is compartmentally separated from the process of translation (in eukaryotes) mRNAs must be exported from the nucleus to the cytoplasm. Transport of mRNA is done through the nuclear membrane, more precisely, nuclear pores. When mRNA gets out to the cytoplasm, it is then transported to particular subcellar destinations thanks to target sequences that help their transport to a specific location.
