The correct answer is: 5S rRNA
In eukaryotes, there are 3 types of DNA dependent RNA polymerases

RNA polymerase I: Transcribes rRNA (28S, 18S, 5.8S)

RNA polymerase II: Transcribes hnRNA (heterogeneous nuclear RNA) a precursor of mRNA

RNA polymerase III: Transcribes tRNA, 5S rRNA & snRNAs (small nuclear RNAs).
