Task: Answer the multiple choice question.
Query: Which compound has a -0.687% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a. CCOc1ccc(/C(O)=C2\C(=O)C(=O)N(CCN(C)C)C2c2cccc(OC)c2OC)cc1Cl
b. CCOCCCNC(C(=O)Nc1ccc(OC)c(Cl)c1)c1ccccc1
c. CC(C)C(NC(=O)CCNC(=O)c1ccc([N+](=O)[O-])cc1)c1nc2ccccc2[nH]1
Answer: a. CCOc1ccc(/C(O)=C2\C(=O)C(=O)N(CCN(C)C)C2c2cccc(OC)c2OC)cc1Cl
