Task: Answer the multiple choice question.
Question: Which compound exhibits a 12.192\% 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, d, or e without using any additional words.
Options:
[a] CSc1nc2cc(Oc3cccc(Cl)c3Cl)c(Cl)cc2[nH]1
[b] CCCOc1ccc(C2C(C(=O)c3ccc(C)o3)=C(O)C(=O)N2Cc2cccnc2)cc1
[c] O=C(Nc1ccccc1Br)C1CCC(=O)N1Cc1ccccc1Cl
[d] Cc1cccc(NC(=O)c2cc(Cl)ccc2[N+](=O)[O-])c1
[e] Cc1nc(NC(=O)CSc2nnc(-c3ccc4c(c3)OCO4)o2)c(Cl)cc1Cl
Answer: b. CCCOc1ccc(C2C(C(=O)c3ccc(C)o3)=C(O)C(=O)N2Cc2cccnc2)cc1
