Task: Answer the multiple choice question.
Query: Which compound exhibits a -1.455\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] COC(=O)c1sc(NC(=O)CCCn2nc([N+](=O)[O-])cc2C)c(C(=O)OC)c1C
[b] CC1CCCCN1C(=S)SC/C(O)=C(\C#N)c1nc2ccccc2[nH]1
[c] Cc1ccc([N+](=O)[O-])cc1N=C(c1ccc([N+](=O)[O-])cc1)N1CCOCC1
[d] O=C(NCCOc1ccccc1Cl)C(=O)Nc1ccccc1
Answer: c. Cc1ccc([N+](=O)[O-])cc1N=C(c1ccc([N+](=O)[O-])cc1)N1CCOCC1
