Task: Answer the multiple-choice question.
Query: Which compound has a -28.027\% 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, or d without using any other words.
Options:
a) CCCCCC(=O)N1CC2(C)CN(C(=O)CCCCC)CC(C)(C1)C2=O
b) O=C(CNC(=O)c1ccccc1)OCC(=O)N1N=C(c2ccc(Cl)cc2)CC1c1ccco1
c) CC(=Nc1ccccc1)C1=C(O)CCCC1=O
d) COC(=O)[C@@H]1C[C@@]2(O)[C@H](O)[C@H](O)[C@H](O)C[C@H]2N1Cc1cc(OC)cc(OC)c1
Answer: b. O=C(CNC(=O)c1ccccc1)OCC(=O)N1N=C(c2ccc(Cl)cc2)CC1c1ccco1
