Answer:

D. RNA polymerase binds to the promoter on the template strand of DNA.

Explanation:

Transcription is the process in which mRNA is formed from the DNA molecules. DNA is a double-stranded molecule but only one strand is used to code the RNA molecule and the strand which is used to code RNA is called the template strand.

RNA polymerase binds on the promoter regions which is present on the template strand and starts transcribing the strand. The complementary sequence is added to make the RNA strand. Therefore the correct answer is D.
