Explanation / Answer

Option A 3' T G T C G G C A T T T 5'

DNA is made up of 3 components, sugar, phosphate group and nitrogenous bases. The nitrogenous base in 1 strand is complementary to other strand. Adenine is complementary to thymine, and guanine to cytosine and vice versa. So making such complimentary pairs, option A shown above in the answer is real sequence for the one given in question.
