Task: Answer the multiple choice question.
Question: Which drug exhibits a -18.541\% human ether-à-go-go related gene (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) Cc1cccc(C(=O)N[C@H](C(=O)OCc2cc(=O)n3c(n2)sc2ccccc23)C(C)C)c1
b) COc1ccc2nc(NC(=O)c3ccoc3C)sc2c1
c) Cc1cccc(C)c1Oc1nc(-c2ccccc2)ncc1S(=O)(=O)c1ccccc1
d) COc1cccc(CN2CCN(Cc3cc(OC)c(OC)cc3[N+](=O)[O-])CC2)c1.O=C(O)C(=O)O
Answer: d. COc1cccc(CN2CCN(Cc3cc(OC)c(OC)cc3[N+](=O)[O-])CC2)c1.O=C(O)C(=O)O
