Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a -19.817\% 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(NCc1ccco1)C1CCCN(S(=O)(=O)c2ccc(Br)cc2)C1
b: O=C(O)C[C@H]1c2cc(C(F)(F)F)ccc2S(=O)(=O)N1C1CCCCC1
c: CCCN(CC(=O)Nc1ccc(F)c(F)c1F)C(=O)c1cc([N+](=O)[O-])ccc1N1CCOCC1
Answer: c. CCCN(CC(=O)Nc1ccc(F)c(F)c1F)C(=O)c1cc([N+](=O)[O-])ccc1N1CCOCC1
