C. RNA polymerase III 3. snRNA

  1. A - 1, B - 2, C - 3

  2. A - 2, B - 1, C - 3

  3. A - 2, B - 3, C - 1

  4. A - 3, B - 2, C - 1

B Correct answer
Explanation

This option is correct because all are correctly matched. RNA polymerase I transcribes rRNAs (28S, 18S and 5.8S). RNA polymerase II transcribes precursor of mRNA, the heterogeneous nuclear RNA (hnRNA). RNA polymerase III is responsible for transcription of tRNA, 5srRNA and snRNAs (small nuclear RNAs).
