Task: Answer the multiple choice question.
Question: Which compound has a 5.045\% 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(NC(=O)CN1C(=O)c2ccccc2C1=O)c1ccccc1
[b] COc1cc(OC)cc(C(=O)N[C@H](C(=O)NCCc2ccc(S(N)(=O)=O)cc2)C(C)C)c1
[c] O=C(NCc1ccco1)c1cc([N+](=O)[O-])ccc1Cl
Answer: c. O=C(NCc1ccco1)c1cc([N+](=O)[O-])ccc1Cl
