    The correct answer will be option-B.

    Explanation:

    Transcription is a process which produces a complementary transcript molecule of DNA called RNA. The RNA formation takes place in three steps: initiation, elongation and termination.

    The initiation step involves a complex enzyme called RNA polymerase which synthesize a complementary strand using one strand of DNA. the enzyme adds a new nucleotide at 3' end of the strand thereby proceeding the reaction in 5' to 3' direction.

    Thus, Option-B is the correct answer.

    RNA polymerase.

    Explanation:

    Transcription may be defined as the process of formation of RNA molecules from the DNA template. The process of translation occurs in the 5' to 3' direction.

    The main enzyme responsible for the transcription is DNA dependent RNA polymerase or RNA polymerase. This enzyme is important for the synthesis of the RNA molecule complementary to the DNA template. RNA pol II is the main transcription enzymes of the mRNA molecule in case of eukaryotes.

    Thus, the correct answer is option (b).
