What is the role of RNA polymerase III in the process of transcription in Eukaryotes?

A $Transcription of rRNAs (28 S, 18 S and 5.8 S)$
B $Transcription of tRNA, 5 S rRNA and snRNA$
C $Transcription of precursor of mRNA$
D $Transcription of only snRNAs$

Solution & Step-by-step Explanation

Eukaryotes have three distinct RNA polymerases:RNA Pol I: Transcribes rRNAs (28 S, 18 S, 5.8 S).RNA Pol II: Transcribes hnRNA (precursor of mRNA).RNA Pol III: Transcribes tRNA, 5S rRNA, and some snRNAs (small nuclear RNAs).
