Task: Answer the multiple-choice question.
Query: Which compound has a 2.194\% 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 additional words.
Options:
a) O=C(CN1CCN(C(=O)c2ccco2)CC1)Nc1ccc(Cl)c(S(=O)(=O)N2CCOCC2)c1
b) CC(C)(C)C1CCC(=NNC(=S)NCc2ccccc2)CC1
c) CN1C(=O)CC(C(=O)Nc2ccccc2F)SC1=Nc1ccc2c(c1)OCO2
d) CC(=C1C(=O)c2ccccc2C1=O)N1CCN(CCN=Cc2c(O)n(C)c(=O)n(C)c2=O)CC1
Answer: a. O=C(CN1CCN(C(=O)c2ccco2)CC1)Nc1ccc(Cl)c(S(=O)(=O)N2CCOCC2)c1
