Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 15.414\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) O=C(OCc1cccc([N+](=O)[O-])c1)c1cccnc1
(b) CC(C)(Oc1ccc(Cl)cc1)C(=O)N1CCN(C(=O)c2ccco2)CC1
(c) O=C1CC[C@@H](O)CCN1CC[C@H](Sc1ccccc1)c1ccccc1
(d) O=C(O)c1cc(O)c2c(c1)C(=O)c1cc(O)cc(O)c1C2=O
Answer: d. O=C(O)c1cc(O)c2c(c1)C(=O)c1cc(O)cc(O)c1C2=O
