Answer:
The first option: AAU - GUU - UGG - UAU
Explanation:
RNA has the nitrogenous bases adenine (A), uracil (U), guanine (G), and cytosine (C). A pairs with U while G pairs with C. The thymine (T) from the DNA must be complemented by the adenine (A) from the RNA, too.
Knowing this, the complementary strand of RNA would be the first option. Another way of finding the answer would be noticing that all the other options have thymine (T), which is a nitrogenous base RNA does not have.
