Task: Answer the multiple choice question.
Question: Which compound has a 0.147\% 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] Cc1cc(C)c(S(=O)(=O)c2cccc(C)c2C)c(=O)[nH]1
[b] O=C(CCc1nnc2ccc(NCc3ccco3)nn12)N1CCN(c2ccccc2F)CC1
[c] CC1CN(C)C(C)C/C1=N/OC(=O)c1ccccc1.Cl
[d] NC(=O)c1ccsc1NC(=O)c1ccc(N2CCCC2=O)cc1
[e] COc1ccc(Nc2nnc(Cc3ccc(Cl)cc3)c(=O)[nH]2)c(OC)c1
Answer: b. O=C(CCc1nnc2ccc(NCc3ccco3)nn12)N1CCN(c2ccccc2F)CC1
