Task: Answer the multiple choice question.
Query: Which compound has a -19.355% 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.) O=[N+]([O-])c1cnccc1Nc1ccc(F)cc1
b.) O=C(OCc1cccc([N+](=O)[O-])c1)c1cccnc1
c.) CO/N=C\c1cc(C(=O)c2ccc(Cl)cc2Cl)cn1C
Answer: b. O=C(OCc1cccc([N+](=O)[O-])c1)c1cccnc1
