Task: Answer the multiple-choice question.
Query: Which drug exhibits a 9.318\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a.) COc1cc([C@@H]2CC=C(C(=O)O)[C@H](c3ccccc3F)N2S(=O)(=O)c2ccc(C)cc2)cc(OC)c1OC
b.) CCn1c(SCC(=O)NCc2ccc3c(c2)OCO3)nnc1-c1c[nH]c2ccccc12
c.) Cc1ccc2nc(-c3ccco3)c(Nc3ccccc3)n2c1
d.) CC1=C([N+](=O)[O-])C(c2cccc(Br)c2)C2=C(N1)c1ccccc1C2=O
Answer: d. CC1=C([N+](=O)[O-])C(c2cccc(Br)c2)C2=C(N1)c1ccccc1C2=O
