Task: Answer the multiple choice question.
Query: Which drug exhibits a 13.469\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] O=C(Cc1ccccc1)NCC1COc2ccccc2O1
[b] CCC(NC(=O)NCc1ccc2c(c1)OCO2)(C(F)(F)F)C(F)(F)F
[c] O=[N+]([O-])c1cc(CS(=O)(=O)Oc2ccc(Cl)cc2)c(O)c([N+](=O)[O-])c1
[d] CCOC(=O)c1cc(C#N)c(Oc2ccccc2OC)nc1-c1ccccc1
Answer: c. O=[N+]([O-])c1cc(CS(=O)(=O)Oc2ccc(Cl)cc2)c(O)c([N+](=O)[O-])c1
