Task: Answer the multiple choice question.
Query: Which drug has a 19.611\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] Cc1cc(C)cc(C(=O)OCC(=O)NC2CCCC2)c1
[b] COc1cc(OC)c(NC(=O)CCNS(=O)(=O)c2ccc3c(c2)CC(C)N3C(C)=O)cc1Cl
[c] Cc1ccc(-c2nccc(-c3ccc([N+](=O)[O-])c(CS(=O)(=O)c4ccc(Cl)cc4)c3)n2)cc1
Answer: c. Cc1ccc(-c2nccc(-c3ccc([N+](=O)[O-])c(CS(=O)(=O)c4ccc(Cl)cc4)c3)n2)cc1
