If in a given DNA molecule a C-G base pair is
changed to a U-G base pair the following
mutational change in the DNA will result
a. C-G to G-C
b. C-G to T-A
c. C-G to A-T
d. C-G to A-U

Can someone elaborate on this for me?

That doesn't really make any sense. If a base gets changed to a uracil in DNA, the cell will go "Hey! Uracil doesn't belong in DNA, it belongs in RNA" and would change it back to cytosine. It'd end up being C-G, just as it began.

Seeing as I just covered DNA repair in genetics, none of those answers seem correct to me.
