Problem statement: Answer the multiple-choice question.
Question: Which drug has a 12.981\% human ether-à-go-go related gene (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] c1cc2c(cc1C1=Nn3c(nnc3C3CCCCC3)SC1)OCO2
[b] CC(C)c1ccc2oc(=O)cc(CN3CCN(c4ccc(F)cc4)CC3)c2c1
[c] O=c1c2ccc(Cl)cc2nc(-c2ccc([N+](=O)[O-])cc2)n1O
Answer: c. O=c1c2ccc(Cl)cc2nc(-c2ccc([N+](=O)[O-])cc2)n1O
