Answer:

The correct answer will be option-true.

Explanation:

The promoter is the sequence of DNA which is located at the 5' upstream of the initiation site. The promoter can contain 100-1000 base pairs which direct the level of the transcription.

It is the presence of these promoters which determines which strand of DNA will be transcripted like anti-sense strand. The promoters work with the other regulatory sequences like silencers and enhancers.

Since it is a sequence of DNA not RNA, thus, option-true is the correct answer.
