Task: Answer the multiple choice question.
Question: Which compound exhibits a 1.966\% 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) COc1ccc(CNC(=O)C2CCN(C(=O)c3sccc3-n3cccc3)CC2)cc1
(b) CC(=O)Nc1ccc(N2CCN(C(C)=O)CC2)cc1
(c) CN(Cc1nccs1)C(=O)c1ccc(OC2CCN(Cc3ccccn3)CC2)cc1
(d) Nc1cc(N)cc(C(=O)OCC(=O)Nc2cc(S(=O)(=O)N3CCCCC3)ccc2Cl)c1
(e) COC(=O)c1c(C)noc1-c1cc(C)on1
Answer: c. CN(Cc1nccs1)C(=O)c1ccc(OC2CCN(Cc3ccccn3)CC2)cc1
