Task: Answer the multiple-choice question.
Query: Which drug exhibits a 8.268\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
(a) O=C(c1ccc2c(c1)N(Cc1ccccc1F)C(=O)c1ccccc1S2(=O)=O)N1CCCC1
(b) CCc1ccc(-c2nc(CN3CCCC(C(=O)NCCc4ccc(OC)c(OC)c4)C3)c(C)o2)cc1
(c) CN1CCc2c(c3c(n2C)CCN(C)[C@@H]3c2cccnc2)[C@H]1c1cccnc1.Cl
(d) COC(=O)c1sc(NC(=O)c2ccc(Cn3cc(Cl)cn3)o2)c(C#N)c1C
(e) CNC(=O)c1cn(-c2ccc(Cl)cc2)c(=O)c2ccccc12
Answer: e. CNC(=O)c1cn(-c2ccc(Cl)cc2)c(=O)c2ccccc12
