Solution
The correct option is A UAGGC
RNA polymerase has the ability to polymerise nucleotides only in a 5’→3’ direction. As the DNA strands are antiparallel. The strand with polarity 3’→5’ is called a template strand which is transcribed into an RNA and the strand with 5’→3’ polarity has the same sequence as RNA(except that uracil replace thymine residues) because of complementarity which is called a coding strand.
So if the coding strand sequence is given then the RNA has the same sequence with the change of thymine with uracil.
