The correct option is A GCUACCGAU
The nitrogen bases for DNA are: thymine (T), guanine (G), cytosine (C) and adenine(A) and for RNA they are adenine, guanine, cytosine and uracil (U). G pairs with C and U pairs with A during transcription. Transcription is the system that produces a complementary RNA sequence from a strand of DNA. Thus, the correct answer is option A.
