(B) In eukaryotic cells,there are three main types of $RNA$ involved in protein synthesis: $mRNA$ (messenger $RNA$),$tRNA$ (transfer $RNA$),and $rRNA$ (ribosomal $RNA$).Correspondingly,there are three distinct types of $RNA$ polymerases responsible for their transcription:$1$. $RNA$ polymerase $I$ transcribes $rRNAs$ ($28S, 18S,$ and $5.8S$).$2$. $RNA$ polymerase $II$ transcribes the precursor of $mRNA$,the heterogeneous nuclear $RNA$ $(hnRNA)$.$3$. $RNA$ polymerase $III$ transcribes $tRNA$,$5S$ $rRNA$,and $snRNAs$ (small nuclear $RNAs$).Therefore,there are $3$ types of $RNA$ and $3$ types of $RNA$ polymerases.

In a eukaryotic cell,how many types of $RNA$ and $RNA$ polymerases are found,respectively?
