Task: Answer the multiple choice question.
Query: Which drug has a -19.619% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] COc1ccccc1NC(=O)c1ccc([N+](=O)[O-])cc1[N+](=O)[O-]
[b] CC(=O)NC1C(Oc2ccc(C)cc2)OC2COC(c3ccco3)OC2C1O
[c] Oc1ccc(Cl)cc1C1=NCCNC(C(F)(F)C(F)F)=C1
Answer: a. COc1ccccc1NC(=O)c1ccc([N+](=O)[O-])cc1[N+](=O)[O-]
