Solution

The correct option is B RNA polymerase
RNA polymerase holoenzyme binds to the promoter, unwinds DNA (open complex) and forms phosphodiester links between the initiating nucleotides.
DNA polymerase, DNA ligase & DNA helicase are involved in the process of replication and not transcription.
