What enzyme complex is responsible for transcription?
a. dna polymerase
b. rna polymerase
c. hexokinase
d. amylase

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.
