Best answer
The correct choice is (a) RNA polymerase

Explanation: In the central dogma of DNA there are two main processes, they are transcription and translation. During the process of transcription, a portion of the DNA is copied into a new mRNA strand. This is done with the help of the RNA polymerase. In translation, the copied mRNA strand is used to produce proteins.
