Explanation:
Detailed explanation-1: -The enzyme that converts DNA into mRNA is called RNA polymerase, which attaches to the DNA double helix as shown here. Once attached, RNA polymerase can unwind the helix and begin copying one of the DNA strands to form an mRNA transcript of the gene.
Detailed explanation-2: -The sequence for AACGTAACG in mRNA molecule synthesized after transcription from a DNA strand shall be UUGCAUUGC. In an RNA strand, the genetic code follows the sequence of A-U, G-C, and T-A. Thus, by this genetic coding, the correct answer is option B.
