Task: Answer the multiple-choice question.
Query: Which drug has a 8.283\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) CC(=O)Nc1c(C)ccc(CNC(=O)COc2cc(C)ccc2C)c1C
(b) C=CCN(c1ccccc1)S(=O)(=O)c1cccc(C(=O)NCC(c2ccccc2OC)N2CCCC2)c1
(c) O=[N+]([O-])c1cc(S(=O)(=O)NCCc2ccccn2)ccc1Cl
Answer: c. O=[N+]([O-])c1cc(S(=O)(=O)NCCc2ccccn2)ccc1Cl
