Task: Answer the multiple choice question.
Question: Which compound has a 8.227\% 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: O=C(c1ccco1)N1CCN(c2ncnc3c2[nH]c2ccc(Cl)cc23)CC1
b: O=C(Cc1ccc(F)cc1)OCN1C(=O)c2ccccc2C1=O
c: CC(C)C1=CC2=CCC3C(C)(C(=O)[O-])CCCC3(C)C2CC1.CC(C12CC3CC(CC(C3)C1)C2)[N+](C)(C)C
d: CC1CCN(C(=O)Cn2c(SCC(=O)Nc3nccs3)nc3ccccc32)CC1
Answer: b. O=C(Cc1ccc(F)cc1)OCN1C(=O)c2ccccc2C1=O
