Task: Answer the multiple-choice question.
Query: Which drug exhibits a -3.699\% 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)N1CCN(C(=S)c2ccc([N+](=O)[O-])cc2)CC1
[b] O=C(Nc1ccc(Cl)cn1)c1ccccc1SCc1ccccc1
[c] O=C(NC1CCSc2ccccc21)c1cccc([N+](=O)[O-])c1
Answer: c. O=C(NC1CCSc2ccccc21)c1cccc([N+](=O)[O-])c1
