Task: Answer the multiple-choice question.
Question: Which drug exhibits a -2.763\% 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] COc1ccc(CNC(=O)C(C)N(C)Cc2cccc(F)c2)cc1
[b] O=C(CCNS(=O)(=O)c1ccc(OC(F)(F)F)cc1)N1CCN(C/C=C/c2ccccc2)CC1
[c] O=C(NCCNc1ccc([N+](=O)[O-])cc1C(F)(F)F)c1ccccc1
Answer: c. O=C(NCCNc1ccc([N+](=O)[O-])cc1C(F)(F)F)c1ccccc1
