Task: Answer the multiple-choice question.
Question: Which drug has a 7.976\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
(a) CCOc1nc(SCCOc2ccccc2)nc(N(C)C)n1
(b) O=C(COc1ccccc1[N+](=O)[O-])Nc1cc(Cl)ccc1C(=O)O
Answer: b. O=C(COc1ccccc1[N+](=O)[O-])Nc1cc(Cl)ccc1C(=O)O
