Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a -2.530\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: COc1ccc(Cl)cc1NCC(=O)Nc1ccc(OC)c(S(=O)(=O)N2CCCCC2)c1
b: CN(C)C(=S)Nc1ccc(S(=O)(=O)N2CCCCC2)cc1
c: O=C(CN1CCN(S(=O)(=O)c2ccccc2[N+](=O)[O-])CC1)Nc1ccc(N2CCOCC2)cc1
Answer: c. O=C(CN1CCN(S(=O)(=O)c2ccccc2[N+](=O)[O-])CC1)Nc1ccc(N2CCOCC2)cc1
