Task: Answer the multiple choice question.
Query: Which compound has a 9.278\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a COc1ccc(C2/C=C\CN(C(=O)C3CCCCC3)CC(=O)N2Cc2ccc(F)cc2)cc1
b Cc1cccc(C(=O)OCCN2CCOCC2)c1.Cl
c O=C(N/N=C/C=C\c1ccc([N+](=O)[O-])cc1)c1cccnc1
d Cc1cc(C(=O)Nc2ccc(Br)cc2)c2ccccc2n1
Answer: c. O=C(N/N=C/C=C\c1ccc([N+](=O)[O-])cc1)c1cccnc1
