Problem statement: Answer the multiple choice question.
Question: Which drug has a 1.804\% 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] COc1ccc(N2CC(NS(=O)(=O)c3ccc(F)cc3)CC2=O)cc1
[b] c1ccc(Oc2nc(NCc3ccco3)nc(NCc3ccco3)n2)cc1
[c] Cc1nc([N+](=O)[O-])c(C(=O)OCc2ccccc2Br)n1C
Answer: c. Cc1nc([N+](=O)[O-])c(C(=O)OCc2ccccc2Br)n1C
