Task: Answer the multiple choice question.
Question: Which compound has a -67.401\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: O=S(=O)(Cc1ccccc1)NCCc1ccc(F)cc1
b: CCn1c(=O)c(C(=O)CN2CCN(Cc3ccc4c(c3)OCO4)CC2)c(N)n(Cc2ccccc2)c1=O
c: c1coc(C2OCC3(CO2)COC(c2ccco2)OC3)c1
Answer: b. CCn1c(=O)c(C(=O)CN2CCN(Cc3ccc4c(c3)OCO4)CC2)c(N)n(Cc2ccccc2)c1=O
