Task: Answer the multiple-choice question.
Question: Which compound exhibits a 8.528\% 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 other words.
Options:
(a) CC(=O)Nc1cccc(N=NN2CCOCC2)c1
(b) CC1(C)CC(=O)C(N=Nc2cc(C(F)(F)F)ccc2Cl)=C(O)C1
(c) CC1(C)OC2OC(COC(=O)c3ccc([N+](=O)[O-])cc3)C3OC(C)(C)OC3C2O1
(d) O=C(/C=C/c1ccco1)NC(=S)NNC(=O)c1ccco1
(e) Cc1ccc(CN(C)C(=O)COC(=O)CSc2ccc([N+](=O)[O-])cc2)cc1
Answer: b. CC1(C)CC(=O)C(N=Nc2cc(C(F)(F)F)ccc2Cl)=C(O)C1
