Task: Answer the multiple-choice question.
Query: Which compound has a 4.269\% 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] O=C(c1cccc(C(F)(F)F)c1)N1CCOc2ccccc21
[b] CC(C)(C)c1ccc(-c2nnc(SCC(=O)O)n2N)cc1
[c] O=C(NC12CC3CC(CC(C3)C1)C2)c1cc([N+](=O)[O-])ccc1N1CCOCC1
Answer: a. O=C(c1cccc(C(F)(F)F)c1)N1CCOc2ccccc21
