Task: Answer the multiple choice question.
Question: Which drug has a -9.329\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: COc1ccc(C(=O)COC(=O)Cc2c[nH]c3ccccc23)c(OC)c1
b: O=C(NCCOc1ccccc1F)c1cc([N+](=O)[O-])ccc1N1CCOCC1
c: CCSc1ccc([C@@H]2[C@H]3C(=O)N(CC)C(=O)[C@H]3[C@]3(C(=O)OC)CCCCN23)cc1.O=C(O)C(F)(F)F
d: CCC(C)n1c(SCc2ccccc2)nc2ccsc2c1=O
Answer: b. O=C(NCCOc1ccccc1F)c1cc([N+](=O)[O-])ccc1N1CCOCC1
