Task: Answer the multiple-choice question.
Query: Which drug exhibits a 8.871\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) COc1ccc(CCNCc2sccc2C)cc1.Cl
(b) COc1ccc(OC)c(CN(CCN2CCOCC2)C(=O)Nc2cccc(Cl)c2)c1
(c) CC(C(=O)Nc1cccc([N+](=O)[O-])c1)N(c1ccccc1)S(C)(=O)=O
(d) N#CC1=C(N)OC2=C(CC/C2=C\c2ccc(F)cc2)C1c1ccc(F)cc1
Answer: b. COc1ccc(OC)c(CN(CCN2CCOCC2)C(=O)Nc2cccc(Cl)c2)c1
