(A) The correct answer is $A$ (hnRNA).In eukaryotes,there are three types of $RNA$ polymerases in the nucleus.$1$. $RNA$ polymerase $I$ transcribes $rRNA$ ($28S, 18S,$ and $5.8S$).$2$. $RNA$ polymerase $II$ transcribes the precursor of $mRNA$,which is known as heterogeneous nuclear $RNA$ $(hnRNA)$.$3$. $RNA$ polymerase $III$ is responsible for the transcription of $tRNA$,$5S$ $rRNA$,and $snRNA$ (small nuclear $RNA$).

$RNA$ polymerase $II$ is responsible for the transcription of . . . . . .
