The RNA polymerase II transcribes:

hnRNA

The correct answer is Option (2) → hnRNA

In eukaryotes, there are  at least three RNA polymerases in the nucleus (in addition to the RNA polymerase found in the organelles). There is a clear cut division of labour.

(i) The RNA polymerase I transcribes rRNAs (28S, 18S, and 5.8S).

(ii) RNA polymerase III is responsible for transcription of tRNA, 5srRNA, and snRNAs (small nuclear RNAs).

(iii) The RNA polymerase II transcribes precursor of mRNA, the heterogeneous nuclear RNA (hnRNA).
