Solution

The correct option is C UAGACCGCA
The base complementarity occurs between adenine and thymine/uracil or guanine and cytosine. As from the template strand, RNA has to be transcribed so the growing RNA strand will incorporate uracil in it complementary to adenine. The growing strand can only incorporate thymine complementary to adenine when it is a DNA.

So, the correct option is 'UAGACCGCA'.
