Task: Answer the multiple choice question.
Query: Which compound has a 11.668\% 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 CCOC(=O)CNC(=O)C1c2cc(OC)c(OC)cc2C(=O)N(C)C1c1ccccc1F
b O=C(Cc1ccccc1[N+](=O)[O-])NCc1ccco1
c COc1cc(OC)c(NC(=O)CCc2nc(-c3cccs3)no2)cc1Cl
Answer: b. O=C(Cc1ccccc1[N+](=O)[O-])NCc1ccco1
