Problem statement: Answer the multiple-choice question.
Question: Which drug has a 0.012\% 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 additional words.
Options:
a: O=C(Nc1nnc(-c2ccc(F)cc2)o1)c1cccc([N+](=O)[O-])c1
b: COc1ccc(S(=O)(=O)N2CN3CCN(C3)C2)cc1
c: Cn1c(=O)c2c(ncn2CC(=O)OCC(=O)Nc2ccc(Cl)cc2)n(C)c1=O
Answer: a. O=C(Nc1nnc(-c2ccc(F)cc2)o1)c1cccc([N+](=O)[O-])c1
