Answer:

The correct answer is B, UAGCGGAAU. The m-RNA molecule is created through complementary base pairing, in which the DNA strand is read in the 5' to 3' direction and the m-RNA is created in the 3' to 5' direction. Thus, A is replaced by U, T is replaced by A, C is replaced by G and G is replaced by C. Therefore, the correct m-RNA would be UAGCGGAAU.
