Task: Answer the multiple choice question.
Question: Which compound exhibits a 0.128\% 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] CN=C1SC(CC(=O)Nc2ccc(C(=O)O)cc2)C(=O)N1C
[b] Cc1cc(=O)oc(C)c1C(=O)Nc1ccc2ncccc2c1
[c] CCC(=O)Nc1cccc(C2=NOC3(C2)C[C@H](C(N)=O)N(C(=O)c2ccc(Cl)cc2)C3)c1
[d] COc1cc2c(cc1OC)C(NC(=O)c1ccc(C)cc1)CC2=O
[e] O=C(O)c1ccc(N/N=C/c2cn(Cc3ccccc3F)c3ccccc23)cc1
Answer: b. Cc1cc(=O)oc(C)c1C(=O)Nc1ccc2ncccc2c1
