Task: Answer the multiple-choice question.
Question: Which compound exhibits a 6.853\% 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: O=C(/C=C/c1ccco1)Nc1cccc2cccnc12
b: COC(=O)C1=C(c2cc3ccccc3s2)C[C@@H]2CC[C@H]1N2C(=O)NCCNC(C)=O
c: CNC(=O)c1c(NC(=O)CCS(=O)(=O)c2ccc(C)cc2)sc2c1CCN(C(=O)OC)C2
d: COc1ccc(/C=N/Nc2nnc(C)n2N)cc1OC(C)=O.Cl
e: Cc1nn(C)c(C(=O)Nc2cccc(CN3CCOCC3)c2)c1Br
Answer: b. COC(=O)C1=C(c2cc3ccccc3s2)C[C@@H]2CC[C@H]1N2C(=O)NCCNC(C)=O
