Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 18.814\% human ether-à-go-go related gene (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: CCOCCCNc1ccc(N2C(=O)CCCC2=O)cc1[N+](=O)[O-]
b: CCOC(=O)c1c(C)n(CC)c2ccc(OC(=O)c3ccc([N+](=O)[O-])cc3)cc12
c: O=C(CN1CCN(C(=O)C2CCCO2)CC1)Nc1c(Cl)cccc1Cl
Answer: c. O=C(CN1CCN(C(=O)C2CCCO2)CC1)Nc1c(Cl)cccc1Cl
