Task: Answer the multiple choice question.
Query: Which compound has a -1.922% 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) Cc1cccc(NC(=O)c2ccc(NC(C)c3ccccc3)c([N+](=O)[O-])c2)n1
(b) O=C(NCc1cccnc1)Nc1ccccc1C(F)(F)F
(c) CCCCC(CC)C(=O)NCc1ccc(F)cc1
Answer: b. O=C(NCc1cccnc1)Nc1ccccc1C(F)(F)F
