Answer:

The correct answer is (A) gene A is a positive regulator of gene B.

Explanation:

When positive regulation occurs a transcription factor is required to bind at the promoter in order to enable RNA polymerase to start transcription.

RNA means ribonucleic acid and it is a long single-stranded chain of cells that processes protein.
