Whereas bacterial cells typically possess only one type of rna polymerase, most eukaryotic cells possess distinct types of rna polymerase. 2 12 4 7 3

The correct answer will be option- three RNA polymerase

Explanation:

The RNA polymerase is the enzyme which helps the process of formation of RNA from DNA during transcription.

Prokaryotes possess only one type of RNA polymerase which form all type of RNA whereas the eukaryotes possess three types of RNA called RNA polymerase I RNA, polymerase II and RNA polymerase III.

These RNA polymerases catalyse the synthesis of different RNA in eukaryotes as RNA polymerase I help in the synthesis of rRNA, RNA polymerase II in miRNA, mRNA, snoRNA and  RNA polymerase III in 5S rRNA and tRNA.

Thus, three RNA polymerase is the correct answer.
